<div>Hello,<br />
My name is Wojciech Dłubacz. I'm student of Informatics and Econometric on University of Science and Technology in Cracow. Actually I'm mastering data-mining and AI techniques. My hobby is programming, I'm trying to focus (ofc focus my hobby, not what I'll do as my job) on client-web-based programming languages and libraries. I used to use mootools library but now I'm learning jQuery, as an act of growing up.<br />
At the moment I don't have any portfolio to show but it will change precipitously.</div>Sahadarhttps://microformats.org/wiki/index.php?title=hcalendar-pl&diff=43224hcalendar-pl2010-10-31T23:14:38Z<p>Sahadar: /* Poprawki i aktualizacje */</p>

=== Poprawki i aktualizacje ===<br />
Znane oraz wychwycone błędy jak i problemy zostały poprawione w [[hcalendar-issues-resolved|rozwiązanych]] i [[hcalendar-issues-closed|zamkniętych]] wątkach. Zanim zaczniesz zgłaszać jakikolwiek [[hcalendar-issues|błąd/problem]], proszę sprawdź powyższe linki.<br />
<br />
Szczególnie zwróć uwagę na wątek "[[dtend-issue]]" poruszający kwestie dat końcowych. Implementacje powinny implementować poprawione błędy możliwie jak najszybciej oraz [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm powinny być przetestowane].<br />
<br />
Aktualnie zajmujemy się aktualizacją do hCalendar 1.0.1 włączając w to również korekcje zarówno składni jak i [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />
BEGIN:VEVENT<br />
URL:http://conferences.oreillynet.com/pub/w/40/program.html<br />

SUMMARY:Web 2.0 Conference<br />
LOCATION:Argent Hotel\, San Francisco\, CA<br />
END:VEVENT<br />
END:VCALENDAR<br />
</nowiki><br />
</pre><br />
<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />
<br />

<br />
----<br />
<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />
BEGIN:VEVENT<br />
URL:http://conferences.oreillynet.com/pub/w/40/program.html<br />

SUMMARY:Web 2.0 Conference<br />
LOCATION:Argent Hotel\, San Francisco\, CA<br />
END:VEVENT<br />
END:VCALENDAR<br />
</nowiki><br />
</pre><br />
<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />
<br />

<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />
BEGIN:VEVENT<br />
URL:http://conferences.oreillynet.com/pub/w/40/program.html<br />

DTEND:20051008<br />
SUMMARY:Web 2.0 Conference<br />
LOCATION:Argent Hotel\, San Francisco\, CA<br />
END:VEVENT<br />
END:VCALENDAR<br />
</nowiki><br />
</pre><br />
<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />
<br />

<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />
BEGIN:VEVENT<br />

</nowiki><br />
</pre><br />
<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
----<br />
<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

== Status ==<br />
hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />

</nowiki><br />
</pre><br />
<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

== Status ==<br />
hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />

</pre><br />
<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />

<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />

== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />

<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

== Status ==<br />
hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />

<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

== Status ==<br />
hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />

<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

== Status ==<br />
hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

== Status ==<br />
hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />
{{rfc-2119-intro}}<br />
<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />

== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />

<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />
VERSION:2.0<br />

<br />
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.<br />

Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />

<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />

'''Required:'''<br />

* '''summary'''<br />

* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />

Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

==Instrukcje==<br />
<br />
Ten artykuł jest głównym źródłem wiedzy o mikroformatach. Znajdziesz tu między innymi specyfikacje najnowszych wersji mikroformatów, wzory stosowania oraz pomocne narzędzia. Ten wiki posiada również wiele stron poświęconych najnowszym rozwiązaniom, oraz mikroformatom które dopiero są w trakcie tworzenia.<br />
<br />
Aby rozpocząć przygodę z mikroformatami:<br />
<br />
* Na początku, bądź zaznajomiony w pisaniu stron i aplikacji zgodnych z semantyką oraz bogatych w opisy , ‘[http://microformats.org/wiki/posh <abbr title="Plain Old Semantic HTML">POSH</abbr>]’ <abbr title="HyperText Mark-up Language">HTML</abbr>.<br />
* Zdobywaj wiedzę o mikroformatach z [http://microformats.org/about/ about page], [http://microformats.org/ blog], [[press|prasa]], [[presentations|prezentacje]], [[books|książki]], [[podcasts|audycje]] i [[screencasts|prezentacje multimedialne]].<br />
* Spójrz na ustabilizowane mikroformaty takie jak [[hcard|hCard]] i [[hcalendar|hCalendar]], a następnie podążaj za [[hcard-examples|przykładami]] aby móc rozpocząć publikacje własnych mikroformatów.<br />
* Masz pytania? Przeczytaj [[faq|najczęściej zadawane pytania]] i zobacz [[glossary|słownik]] dla terminów i definicji. Możesz również pisać w {{MicroformatsMailingList}}.<br />
* Chcesz nauczyć się więcej? Zobacz na [[events|wydarzenia]] w świecie mikroformatów.<br />
<br />
==Definicje==<br />
Mikroformaty są to wzory kodu HTML reprezentujące powszechnie publikowane rzeczy takie jak: [[hcard|dane personalne]], [[hcalendar|wydarzenia]], [[hatom|posty w blogach]], [[hreview|przeglądy]] i [[rel-tag|tagi]] na stronach internetowych.<br />
<br />
Mikroformaty pozwalają publikować bardziej dokładnie informacje w sieci; są najprostszą i najszybszą drogą do zapewnienia zgodności z urządzeniami oraz programami mobilnymi dla Twoich informacji na stronie.<br />
<br />
* Przeczytaj więcej opisów o tym do czego służą mikroformaty na stronach: [[what-are-microformats|co to są mikroformaty]], oraz [[what-can-you-do-with-microformats|co możesz zrobić przy pomocy mikroformatów]].<br />

== Status ==<br />
hCalendar 1.0 is a microformats.org specification. Public discussion on hCalendar takes place on [[hcalendar-feedback]], the #microformats [[irc]] channel on irc.freenode.net, and [http://microformats.org/discuss/mail/microformats-discuss/ microformats-discuss mailing list].<br />
<br />
=== Available languages ===<br />
The English version of this specification is the only normative version. For translations of this document see the [[#translations]] section.<br />
<br />
=== Errata and Updates ===<br />
Known errors and issues in this specification are corrected in [[hcalendar-issues-resolved|resolved]] and [[hcalendar-issues-closed|closed]] issues. Please check there before reporting [[hcalendar-issues|issues]].<br />
<br />
Note in particular the [[dtend-issue]] which affects end dates. Implementations {{should}} implement the issue resolution ASAP and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
The hCalendar 1.0.1 update is currently under development and incorporates known errata corrections as well as the [[value-class-pattern]].<br />
<br />
== Introduction ==<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), has been broadly interoperably implemented (e.g. Apple's "iCal" application built into MacOSX).<br />
<br />
In addition, bloggers often discuss events on their blogs -- upcoming events, writeups of past events, etc. With just a tad bit of structure, bloggers can discuss events in their blog(s) in such a way that spiders and other aggregators can retrieve such events, automatically convert them to iCalendar, and use them in any iCalendar application or service.<br />
<br />
This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic HTML. Bloggers can both embed hCalendar events directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCalendar enables applications to retrieve information about such events directly from web pages without having to reference a separate file.<br />
<br />

<br />
== Semantic XHTML Design Principles ==<br />
<br />
{{semantic-xhtml-design-principles}}<br />
<br />
For practical implementations, it should be noted that Internet Explorer's support for styling <code><nowiki><abbr></nowiki></code> elements is poor, and may require wrapper elements.<br />
<br />
== Format ==<br />
=== In General ===<br />
The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.<br />
<br />
Note: the editor and authors of this specification are tracking the [http://lists.osafoundation.org/pipermail/ietf-calsify/ "iCal-Basic" effort] and intend to base the core hCalendar profile on iCal-Basic. See references for a link to the current draft.<br />
<br />
The basic format of hCalendar is to use iCalendar object/property names in lower-case for class names, and to map the nesting of iCalendar objects directly into nested XHTML elements.<br />
<br />
=== Root Class Name ===<br />
The root class name for hCalendar is "vcalendar". An element with a class name of "vcalendar" is itself called an ''hCalendar''. <br />
<br />
The root class name for events is "vevent". An element with a class name of "vevent" is itself called an ''hCalendar event''.<br />
<br />
For authoring convenience, both "vevent" and "vcalendar" are treated as root class names for parsing purposes. If a document contains elements with class name "vevent" but not "vcalendar", the entire document has an implied "vcalendar" context.<br />
<br />
'''vevent''' should be considered required for each event listing.<br />
<br />
=== Properties and Sub-properties ===<br />
The properties of an hCalendar are represented by elements inside the hCalendar. Elements with class names of the listed properties represent the values of those properties. Some properties have sub-properties, and those are represented by elements inside the elements for properties.<br />
<br />
=== Property List ===<br />
hCalendar properties (sub-properties in parentheses like this)<br />
<br />
'''Required:'''<br />
* '''dtstart''' ([[iso-8601|ISO date]])<br />
* '''summary'''<br />
Optional:<br />
* location<br />
* url<br />
* dtend (ISO date), duration (ISO date duration)<br />
* rdate, rrule<br />
* category, description<br />
* uid<br />
* geo (latitude, longitude)<br />
* attendee (partstat, role), contact, organizer<br />
* attach<br />
* status<br />
* ... editor's note: this list is incomplete (an incomplete list is better than no list) and is being currently edited from RFC2445 to here. The above list of properties are those that are often used in hCalendar on the web.<br />
<br />
=== Profile ===<br />
The hCalendar XMDP profile is at http://microformats.org/profile/hcalendar<br />
<br />
Content that uses hCalendar {{should}} reference this profile, e.g.<br />
<source lang=html4strict><br />
<head profile="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
<link rel="profile" href="http://microformats.org/profile/hcalendar"><br />
</source><br />
or<br />
<source lang=html4strict><br />
This content uses <a rel="profile" href="http://microformats.org/profile/hcalendar">hCalendar</a>.<br />
</source><br />
Content may combine the above methods as well.<br />
<br />
=== More Semantic Equivalents ===<br />
For some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:<br />
* <code>URL</code> in iCalendar becomes <code>&lt;a class="url" href="..."&gt;...&lt;/a&gt;</code> inside the element with <code>class="vevent"</code> in hCalendar.<br />
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar {{may}} be represented by an [[hcard|hCard]] in hCalendar .<br />
* A named <code>LOCATION</code> (potentially with an address and/or geo) in iCalendar {{may}} be represented by a nested [[hcard|hCard]] in hCalendar. Similarly, an address <code>LOCATION</code> {{may}} be represented by an [[adr]], and a geo (latitude and longitude) <code>LOCATION</code> may be represented by a [[geo]].<br />
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.<br />
* <code>ATTACH</code> in iCalendar becomes an img or object element (where the value is stored ito / retrieved from the 'src' or 'data' attributes respectively). An <code>&lt;a class="attach" href="..."&gt;...&lt;/a&gt;</code> may also be used, in which case the 'href' attribute is used for the property value.<br />
<br />
=== Singular vs. Plural Properties ===<br />
<br />
For properties which are singular (e.g. "N" and "FN" from vCard), the first descendant element with that class {{should}} take effect, any others being ignored.<br />
<br />
For properties which can be plural (e.g. "TEL" from vCard), each class instance {{should}} create a instance of that property. Plural properties with subtypes (e.g. TEL with WORK, HOME, CELL from vCard) can be optimized to share a common element for the property itself, with each instance of subtype being an appropriately classed descendant of the property element.<br />
<br />
==== Plural Properties Singularized ====<br />
<br />
Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.<br />
<br />
=== Human vs. Machine readable ===<br />
If an <code><nowiki><abbr></nowiki></code> element is used for a property, then the '<code>title</code>' attribute of the <code><nowiki><abbr></nowiki></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value. This specification recommends that such <code><nowiki><abbr></nowiki></code> elements be used for the following iCalendar properties:<br />
* DTSTART, DTEND, DURATION, RDATE, RRULE<br />
<br />
== Examples ==<br />
<br />
Here is a sample multiple-day event in an iCalendar:<br />
<pre><br />
<nowiki><br />
BEGIN:VCALENDAR<br />
PRODID:-//XYZproduct//EN<br />

<br />
Note 1: that this is a '''live''' hCalendar microformat, which will be found on this page by parsers.<br />
<br />
Note 2: This example used to have "2005-10-08" as the value of the dtend, but per the resolution to the [[dtend-issue]], has been changed to "2005-10-07" in order to encourage publishers/implementers to update their markup/code immediately and [http://ufxtract.com/testsuite/hcalendar/hcalendar1.htm test it].<br />
<br />
Note 3: Note that the iCalendar in the first part of the example has the code <code>DTEND:20051008</code>. That "8" is not a typo. iCalendar uses <em>exclusive</em> whole end dates (DTEND values) and thus requires that the DTEND value be set to a whole day <em>after</em> what content publishers visibly display as the ending date of an event. iCalendar's exclusive end dates convention has shown to be [[dtend-issue|problematic and confusing]] for content authors and publishers. Thus per the resolution to the [[dtend-issue]], in hCalendar, the end date is stated exactly as existing events publish visible end dates to humans, with an <em>inclusive</em> end date (dtend property value), in this example, 2005-10-07.<br />

<br />
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.<br />
<br />
Note 2: A surrounding <code><nowiki><span class="vcalendar"></nowiki></code> element is optional, and is left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.<br />
<br />
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.<br />
<br />
Note 4: [[iso-8601|ISO8601]] datetimes (required by iCalendar) are not very human friendly. In addition, the year is often understood implicitly by humans from the context. Thus <code><nowiki><abbr></nowiki></code> elements are used to simultaneously provide a human friendly date and/or time in the visible contents of the element, while placing the respective machine parsable comprehensive ISO8601 datetime in the 'title' attribute.<br />
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339. '''Update: Per the [[value-class-pattern]], separate dates and times {{should}} be used by authors rather than a full ISO8601 datetime, for better readability and listenability.'''<br />
<br />
Note 5: Per the [[dtend-issue]] resolution, DTEND dates are provided as humans expecte them to be (consistent with what day an event ends on), rather than iCalendar's confusing definition (the day after). Thus hCalendar processors which produce iCalendar must make the transformation, which is to treat a whole hCalendar <code>dtend</code> end date as *inclusive*, and convert it to an *[http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html exclusive DTEND]* end date when producing iCalendar.<br />
<br />
Note 6: The location in this example contains implicit structure (venue name, city, state) which could be marked up explicitly as an [[hcard|hCard]]. See [http://microformats.org/wiki/hcalendar-brainstorming#hCard_locations hCalendar brainstorming: hCard locations] for a informative explanation of how to do this.<br />

Ten artykuł jest głównym źródłem wiedzy o mikroformatach. Znajdziesz tu między innymi specyfikacje najnowszych wersji mikroformatów, wzory stosowania oraz pomocne narzędzia. Ten wiki posiada również wiele stron poświęconych najnowszym rozwiązaniom, oraz mikroformatom które dopiero są w trakcie tworzenia.<br />
<br />
Aby rozpocząć przygodę z mikroformatami:<br />
<br />
* Na początku, bądź zaznajomiony w pisaniu stron i aplikacji zgodnych z semantyką oraz bogatych w opisy , ‘[http://microformats.org/wiki/posh <abbr title="Plain Old Semantic HTML">POSH</abbr>]’ <abbr title="HyperText Mark-up Language">HTML</abbr>.<br />
* Zdobywaj wiedzę o mikroformatach z [http://microformats.org/about/ about page], [http://microformats.org/ blog], [[press|prasa]], [[presentations|prezentacje]], [[books|książki]], [[podcasts|audycje]] i [[screencasts|prezentacje multimedialne]].<br />
* Spójrz na ustabilizowane mikroformaty takie jak [[hcard|hCard]] i [[hcalendar|hCalendar]], a następnie podążaj za [[hcard-examples|przykładami]] aby móc rozpocząć publikacje własnych mikroformatów.<br />
* Masz pytania? Przeczytaj [[faq|najczęściej zadawane pytania]] i zobacz [[glossary|słownik]] dla terminów i definicji. Możesz również pisać w {{MicroformatsMailingList}}.<br />
* Chcesz nauczyć się więcej? Zobacz na [[events|wydarzenia]] w świecie mikroformatów.<br />
<br />
==Definicje==<br />
Mikroformaty są to wzory kodu HTML reprezentujące powszechnie publikowane rzeczy takie jak: [[hcard|dane personalne]], [[hcalendar|wydarzenia]], [[hatom|posty w blogach]], [[hreview|przeglądy]] i [[rel-tag|tagi]] na stronach internetowych.<br />
<br />
Mikroformaty pozwalają publikować bardziej dokładnie informacje w sieci; są najprostszą i najszybszą drogą do zapewnienia zgodności z urządzeniami oraz programami mobilnymi dla Twoich informacji na stronie.<br />

==Instrukcje==<br />
<br />
Ten artykuł jest głównym źródłem wiedzy o mikroformatach. Znajdziesz tu między innymi specyfikacje najnowszych wersji mikroformatów, wzory stosowania oraz pomocne narzędzia. Ten wiki posiada również wiele stron poświęconych najnowszym rozwiązaniom, oraz mikroformatom które dopiero są w trakcie tworzenia.<br />
<br />
Aby rozpocząć przygodę z mikroformatami:<br />
<br />
* Na początku, bądź zaznajomiony w pisaniu stron i aplikacji zgodnych z semantyką oraz bogatych w opisy , ‘[http://microformats.org/wiki/posh <abbr title="Plain Old Semantic HTML">POSH</abbr>]’ <abbr title="HyperText Mark-up Language">HTML</abbr>.<br />
* Zdobywaj wiedzę o mikroformatach z [http://microformats.org/about/ about page], [http://microformats.org/ blog], [[press|prasa]], [[presentations|prezentacje]], [[books|książki]], [[podcasts|audycje]] i [[screencasts|prezentacje multimedialne]].<br />
* Spójrz na ustabilizowane mikroformaty takie jak [[hcard|hCard]] i [[hcalendar|hCalendar]], a następnie podążaj za [[hcard-examples|przykładami]] aby móc rozpocząć publikacje własnych mikroformatów.<br />
* Masz pytania? Przeczytaj [[faq|najczęściej zadawane pytania]] i zobacz [[glossary|słownik]] dla terminów i definicji. Możesz również pisać w {{MicroformatsMailingList}}.<br />
* Chcesz nauczyć się więcej? Zobacz na [[events|wydarzenia]] w świecie mikroformatów.<br />
<br />
==Definicje==<br />
Mikroformaty są to wzory kodu HTML reprezentujące powszechnie publikowane rzeczy takie jak: [[hcard|dane personalne]], [[hcalendar|wydarzenia]], [[hatom|posty w blogach]], [[hreview|przeglądy]] i [[rel-tag|tagi]] na stronach internetowych.<br />
<br />
Mikroformaty pozwalają publikować bardziej dokładnie informacje w sieci; są najprostszą i najszybszą drogą do zapewnienia zgodności z urządzeniami oraz programami mobilnymi dla Twoich informacji na stronie.<br />
<br />
