===Examples with some problems===
Entries may be moved here if there's a problem with the way hCards are used on the page concerned. If the page is yours, and you want to improve it, see the [[hcard-faq|hCard FAQ]], or raise any queries on [[hcard-issues|hCard Issues]] or [[mailing-lists#microformats-discuss|the mailing list]], where people will be happy to help you.

Examples may also be sorted into the grouped sections below, and noted in a subsection with minor (unTOC'd) heading: '''with some problems:''' (e.g. see [[hcard-examples-in-wild#Institutions|Institutions]]). That way it is easier to keep similar examples grouped together, even if they have problems, so that when the problems are fixed they can simple be moved up a little rather than having to be sorted into the proper group.

Please consider distinguishing problems for each as either:
* '''invalid''' - the hCard is invalid and cannot be parsed by a parser for any information due to the problem.
* '''suboptimal''' - the hCard is technically valid, yet either has one or more properties that have no data due to a markup problem (e.g. adr without children), and/or there is data inside the hCard markup which ''could'' be marked up with an hCard (sub)property but isn't.
* '''hidden''' - one or more the hCard's (sub)properties are hidden via CSS or other mechanism and are thus potentially out-of-date or vulnerable to being labeled as spam by search engines.

hCards with some problems:

* [http://rosebleed.net/ Rosebleed] supports [[hCard user profiles]] - your profile URL is <nowiki>http://rosebleed.net/users/profile.php/</nowiki> followed by your username, e.g. [http://rosebleed.net/users/profile.php/silvermoon82 silvermoon82].
**'''invalid''' The "n" property is empty, that is, it has no explicit sub-properties, which is not allowed. Possible fixes to the content: explicitly markup 'given-name' and 'family-name', or just remove 'n' property from the markup and let 'fn' implied 'n' rule take effect.
***'''Fixed''' profiles now explicitly mark up 'n' where possible, otherwise omits it
* [http://lazylibrary.com LazyLibrary] uses author hCard's on every book page. Example: [http://lazylibrary.com/book/0751370576]

== Grouped Examples ==
This section organizes examples into several rough categories as follows. If an example fits in more than one cateogry, use the *last* matching category in this list that matches the specific hCard example(s) in the wild that you are trying to categorize.
# '''Individuals''' - one card per person, perhaps sort alphabetically by "family-name". People with their own hCards (typically) on their own site.
# '''Organizations''' - one card per organization, alphabetical by "fn". Organizations with their own hCard(s) (typically) on their own site.
# '''Institutions''' - which list more than one person, with a count estimating the # of hCards, e.g. 40k for Avon. Also indicate complexity of information supplied, eg. just name+number vs. complete details. Alphabetically sorted by "org" with perhaps a few individuals listed in a single sub-bullet, comma delimited, sorted by "family-name".
# '''Group Blogs''' - blogs with multiple authors marked up with hCard
# '''Online Profiles''' - which host profiles for more than one person, with a count estimating the # of hCards, e.g. 10m+ for Flickr.com. Alphabetically sorted by "fn" with perhaps a few individuals listed in a single sub-bullet, comma delimited, sorted by "family-name".
# '''Online Venues''' - which provide listings for businesses or organizations, with a count estimating the # of venues, e.g. ~10k for Upcoming.org. Alphabetically sorted by service/site name, with perhaps a few specific venues listed in a single sub-bullet, comma delimited, sorted by "fn".
# '''Speakers Listings''' - event sites' speakers pages where the speakers are marked up with hCard. Sort by date, sub-grouped by year. Most recent first. Perhaps a few individuals listed in a single sub-bullet each event, comma delimited, sorted by "family-name".

In addition there is a separate "UTF8 Examples" section that can be used to put another link to any hCard examples in the wild which exercise various non-ASCII7 / non-english characters for various property values.

As each section itself become quite large (we might be there already, once we sort through the above "Reviewed Examples"), it will probably be moved to a separate page, leaving its heading here in place, and replacing its contents here with a link to the separate page and perhaps a stats summary.

===UTF8 Examples===
These examples all contain one or more characters in UTF8 that are outside the ASCII7 range and make for excellent test cases to make sure you are handling UTF8 properly throughout your hCard parsing and transforming. And especially if you are generating vCards, these test cases will help you make sure you are generating UTF8 vCards in such a way that can be recognized by UTF8 supporting vCard applications. Sorted roughly alphabetically (per Unicode).
* [http://sphinx.net.ru/author/ Dmitry Dzhus] embedded his UTF8 encoded hCard with Russian characters in «Author» page of his website.

<h1> hCalendar </h1>

hCalendar is a simple, open, distributed calendaring and events format, based on the iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]), suitable for embedding in (X)HTML, Atom, RSS, and arbitrary XML. hCalendar is one of several open [[microformats|microformat]] standards.

Want to get started with writing an [[hcalendar|hCalendar]] event? Use the [http://microformats.org/code/hcalendar/creator hCalendar creator] to write up an event and publish it, or follow the [[hcalendar-authoring|hCalendar authoring tips]] to add hCalendar markup to your page of upcoming events or events you mention in blog posts, wikis, etc.

__TOC__

== Specification ==

; Editor : [http://tantek.com/ Tantek Çelik] ([http://technorati.com Technorati, Inc])
; Authors : [http://tantek.com/ Tantek Çelik], [http://technorati.com Technorati, Inc]

=== Inspiration and Acknowledgments ===
Thanks to:
* Adam Bosworth for leading the [http://wiki.oreillynet.com/foocamp04/index.cgi?HTMLForCalendars FOO Camp 2004 HTML For Calendars presentation] which brought together a critical mass of interested parties.

== Introduction ==
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).

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.

This specification introduces the '''hCalendar''' format, which is a 1:1 representation of the aforementioned iCalendar standard, in semantic XHTML. 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.

== Semantic XHTML Design Principles ==

{{semantic-xhtml-design-principles}}

== Format ==

=== In General ===

The iCalendar standard ([http://www.ietf.org/rfc/rfc2445.txt RFC2445]) forms the basis of hCalendar.

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.

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.

=== More Semantic Equivalents ===

However, for some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:
* <code>URL</code> in iCalendar becomes <code><a class="url" href="...">...</a></code> inside the element with <code>class="vevent"</code> in hCalendar.
* <code>ATTENDEE</code>, <code>CONTACT</code>, and <code>ORGANIZER</code> in iCalendar may be represented by an [[hcard|hCard]] in hCalendar .
* 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]].
* <code>UID</code> in iCalendar simply becomes another semantic applied to a specific URL for an hCalendar event.

=== Singular vs. Plural Properties ===

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.

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.

==== Plural Properties Singularized ====

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.

=== Human vs. Machine readable ===
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:
* DTSTART, DTEND, DURATION, RDATE, RRULE

== Example ==

Here is a sample event in an iCalendar:
<pre><nowiki>
BEGIN:VCALENDAR
PRODID:-//XYZproduct//EN
VERSION:2.0
BEGIN:VEVENT
URL:http://www.web2con.com/
DTSTART:20051005
DTEND:20051008
SUMMARY:Web 2.0 Conference
LOCATION:Argent Hotel\, San Francisco\, CA
END:VEVENT
END:VCALENDAR
</nowiki></pre>
and an equivalent event in hCalendar format with various elements optimized appropriately. See [[hcalendar-example1-steps]] for the derivation.

<pre><nowiki>
<span class="vevent">
<a class="url" href="http://www.web2con.com/">
<span class="summary">Web 2.0 Conference</span>:
<abbr class="dtstart" title="2005-10-05">October 5</abbr>-
<abbr class="dtend" title="2005-10-08">7</abbr>,
at the <span class="location">Argent Hotel, San Francisco, CA</span>
</a>
</span>
</nowiki></pre>
which could be displayed as:

[http://www.web2con.com/ Web 2.0 Conference: October 5-7, at the Argent Hotel, San Francisco, CA]

The following example specifies a scheduled meeting that begins
at 8:30 AM EST on March 12, 1998 and ends at 9:30 AM EST on March 12,
1998.

<pre><nowiki>
BEGIN:VCALENDAR
BEGIN:VEVENT
UID:guid-1.host1.com
DTSTAMP:19980309T231000Z
DESCRIPTION:Project XYZ Review Meeting
SUMMARY:XYZ Project Review
DTSTART:19980312T133000Z
DTEND:19980312T143000Z
LOCATION:1CP Conference Room 4350
END:VEVENT
END:VCALENDAR
</nowiki></pre>

The equivalent in hCalendar:

<pre><nowiki>
<div class="vevent">
<h3 class="summary">XYZ Project Review</h3>
<p class="description">Project XYZ Review Meeting</p>
<p>To held on <abbr class="dtstart" title="1998-03-12T08:30:00-05:00">12 March 1998 from 8:30am EST</abbr>
until <abbr class="dtend" title="1998-03-12T09:30:00-05:00">9:30am EST</abbr></p>
<p>Location: <span class="location">1CP Conference Room 4350</span></p>
<small>Booked by: <span class="uid">guid-1.host1.com</span> on <abbr class="dtstamp" title="19980309T231000Z">9 Mar 1998 6:00pm</abbr></small>
</div>
</nowiki></pre>

This could be displayed as:

----

<div class="vevent">
<h3 class="summary">XYZ Project Review</h3>
<p class="description">Project XYZ Review Meeting</p>
<p>To held on <abbr class="dtstart" title="1998-03-12T08:30:00-05:00">12 March 1998 from 8:30am EST</abbr>
until <abbr class="dtend" title="1998-03-12T09:30:00-05:00">9:30am EST</abbr></p>

----

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.

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.

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.

Note 4: ISO8601 dates (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.
The notation <code>YYYY-MM-DDThh:mm:ss</code> should be used for better readability, following the format of RFC 3339.

Note 5: The difference between the DTEND ISO8601 date (2005-10-08) and the human readable date (7) is NOT a mistake. [http://lists.osafoundation.org/pipermail/ietf-calsify/2005-September/000769.html DTEND is exclusive], meaning, that the event ends just before the DTEND. Thus for events which start on one day and end on another day, the DTEND date must be specified as the day after the day that a human would say is the last day of the event.

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.

== Examples in the wild ==
This section is '''informative'''.

The following sites have implemented hCalendar, and thus are a great place to start for anyone looking for examples "in the wild" to try parsing, indexing, organizing etc. If events on your pages are marked up with hCalendar, feel free to add it to the top of this list. Once the list grows too big, we'll make a separate wiki page.

Add your name here if you make significant contributions to this page and wish to take responsibility for them.

== Introduction ==

Tantek Çelik developed [http://gmpg.org/xmdp/ XMDP] to define extensions to XHTML including rel values, class names, and <meta name> properties and values. Per the [http://gmpg.org/xmdp/description XMDP spec], a link to a microformat's XMDP in the profile attribute of head element indicates that that microformat's vocabulary is formally defined in the document. A parser could read the allowed attribute values from the linked XMDP and thus know explicitly which microformats may be in use, and which class names are meant to convey which meanings.

This page is for exploring possible additions / extensions to XMDP.

See [[xmdp-faq]] and [[xmdp-issues]] for questions and issues.

== Possible XMDP Additions ==

=== resolving when microformats may be in use ===

Currently the potential existence of microformats in a document can be declared by referencing the profile URLs for those microformats in the profile attribute of the head element of that document.

Another way would be to include the <nowiki><a rel="profile" href="XMDP URL">powered by microformat xyz</a></nowiki> within the container element for the microformat. The XMDP spec could then specify that when the <a> element is used in this way, it indicates that the microformat is used by the element containing the <a> element.

There are, however, several clear issues with this proposal:

* Not every microformat has a container element. Consider [[rel-tag]] one of the most widely used microformats.
* To some extent, using microformats adds to the cost of writing the document. It's like filling in a form just to write your thoughts. Putting <a> elements with each microformat adds unwanted links on top of that.

=== root class name identification ===

It could be quite convenient for "generic/universal" microformat parsers if they could read an XMDP profile and understand which of the defined class names were ''root'' class names for microformats, and thus be able to distinguish those object boundaries.

One simple thought would be that the ''first'' class name defined in a profile
(e.g. [[hcard-profile]]) is the root class for that microformat. Problems:
* What about an XMDP that defines multiple microformats?
* What about a microformat that defines multiple possible root class names (e.g. [[hcalendar|hCalendar]] permits "vcalendar" or "vevent", [[hatom|hAtom]] permits "hfeed" or "hentry")?

=== linking to the XMDP ===

As hinted in the note on "when microformats may be in use", there are additional methods under discussion for linking to the XMDP in addition to the current method of using the profile attribute of the head element:
* Using <nowiki><link rel="profile" href="link to XMDP"/></nowiki>. This method can be used now and will be formalized in XHTML 2.
** A problem with this method is that it (still) requires access to the head element.
* Using <nowiki><a rel="profile" href="link to XMDP">powered by microformat xyz</a></nowiki> in the body of the document.
** As noted by a number of people, this approach has the added benefit of creating a viral marketing opportunity for the microformats used. For instance, developers could add badges saying they are using microformat xyz as suggested by the example.
** Blog authoring environments allow you to insert links at will, so this squarely <abbr title="avoids">obviates</abbr> the need to access the head element.

=== includes / aggregate profiles===

Methods for including one or more values, properties, or an entire XMDP into an other XMDP as a way of creating an aggregate profile that effectively contains definitions from multiple profiles would be quite useful. They would enable documents with microformats to simply refer to a single profile URL rather than a complete space separated set of all the profile URLs of the microformats that may be in use.

=== vocabulary aliasing ===

An XMDP document could be used to define a microformat profile that is nothing more than a simple dictionary mapping between an existing, non-standard set of HTML classes and the terms in a standard microformat profile. This would allow a publisher to support a given microformat by merely using the URI of a new profile document as the value of an individual document's head/profile attribute, rather than modifying the individual class values throughout each document to conform to an existing profile. Initial suggestion with use case description in this [http://microformats.org/discuss/mail/microformats-discuss/2005-October/001623.html microformats-discuss post]. Note (from [http://microformats.org/discuss/mail/microformats-discuss/2005-October/001633.html Kevin's response]) that HTML class attributes can contain multiple values, e.g. class="post hentry", so a publisher doesn't have to discard their existing class values to use those of a microformat.

=== subclassing / ontology addition ===
One may want to introduce a new property (or value) and base it on an existing property (or value). In this sample XMDP, the value "self" is defined, based on the value "me" from XFN 1.1:

<pre>
<nowiki>
<dl class="rel">
<dt id='self'><a href="http://www.gmpg.org/xfn/11#me" rev="extends">self</a></dt>
<dd>This is a pointer to me, it extends the "me" value of XFN</dd>
</dl>
</nowiki>
</pre>
There are two interesting pieces that have been added, a URL with an anchor to another XMDP profile and a rev attribute. The rev value in
this example is 'extends'. These means that the page this is refering too, is extended by the property SELF. So you could make an XMDP that
lists all the possible rev attributes, 'extends', 'inverse', 'equivalent', etc. Then you could 'alias' one microformat property to another.

A universal XMDP validator/parser/etc could extract data across two or more XMDP profiles and potentially reason between them. This could create a small ontology.

It is not clear if this idea actually has utility or is simply a solution looking for a problem.

=== XMDP XML Schema ===
* [http://www.redantdesign.com/hcard/ XSD and XMDP for Microformats]
The link shows a bad example of creating XMDP from an XSD schema. The big question I guess is why?
Having XMDP defined in XSD should make it easier for machines to read Microformats, rules and strict data typing will allow Microformats to be validated when contained within an XML/XHTML document. If a document is using microformats with and XSD behind simple XPath queries can be used to harvest the information, this can then be rendered to straight XML for translation to RDF or other XML transport formats.

XSD behind XMDP also has distinct advantages for CMS authors, the XSD sitting behind xforms or sxforms to allow data entry into a CMS can be used to generate XMDP and valid Microformats when rendering content. This in theory should make it easier for CMS authors to develop a semantic core around data before exporting to XHTML + Microformats, RDF etc. and/or make data querying via web services a little more straightforward.

==== Follow up ====
Having looked into Microformats a little more I realise how bad that example is; however I still feel that placing a schema behind XMDP is a worthwhile exercise. I don't mind spending a little time on this if anyone feels it's a worthwhile exercise, but I'd propose the following:
* Define a loose set of microformat conventions (i.e. a meta property will be bound to an attribute etc.), and have these defined in a microformat namespace (mf:?).
* Create a XSD for common microformat fields without structures (dtStart etc.), with XSD typing and mf: rules (i.e. mf:optional-html-attribute-binding="title" or mf:html-attribute-binding="href" - names were never my strong point )
* Start working towards creating XSD schema including the common schema for agreed specifications

There would still need to be some form of link between the XMDP and the defining XSD (profile attribute or link element?). With these in place it should be possible for an application like tails, or new apps to pick up on any Microformat in a page and display the data, without the application having to be aware of the specific Microformat standard.

Microformats are cool, especially the fact that you don't have to be a rocket scientist to start using them. However if there can be a way of interleaving grassroots microformat adoption into the more complex semantic forms (RDF etc.), through XML then that's got to be a bonus?

We have an IRC channel, [irc://irc.freenode.net#microformats #microformats on the freenode network].

There's typically someone there at any point during the day, though there isn't always active discussion. Sometimes, though this is the best place to discuss issues that need lots of back and forth discussion.

== Introduction ==

Tantek Çelik developed [http://gmpg.org/xmdp/ XMDP] to define extensions to XHTML including rel values, class names, and <meta name> properties and values. Per the [http://gmpg.org/xmdp/description XMDP spec], a link to a microformat's XMDP in the profile attribute of head element indicates that that microformat's vocabulary is formally defined in the document. A parser could read the allowed attribute values from the linked XMDP and thus know explicitly which microformats may be in use, and which class names are meant to convey which meanings.

This page is for exploring possible additions / extensions to XMDP.

See [[xmdp-faq]] and [[xmdp-issues]] for questions and issues.

== Possible XMDP Additions ==

=== resolving when microformats may be in use ===

Currently the potential existence of microformats in a document can be declared by referencing the profile URLs for those microformats in the profile attribute of the head element of that document.

Another way would be to include the <nowiki><a rel="profile" href="XMDP URL">powered by microformat xyz</a></nowiki> within the container element for the microformat. The XMDP spec could then specify that when the <a> element is used in this way, it indicates that the microformat is used by the element containing the <a> element.

There are, however, several clear issues with this proposal:

* Not every microformat has a container element. Consider [[rel-tag]] one of the most widely used microformats.
* To some extent, using microformats adds to the cost of writing the document. It's like filling in a form just to write your thoughts. Putting <a> elements with each microformat adds unwanted links on top of that.

=== root class name identification ===

It could be quite convenient for "generic/universal" microformat parsers if they could read an XMDP profile and understand which of the defined class names were ''root'' class names for microformats, and thus be able to distinguish those object boundaries.

One simple thought would be that the ''first'' class name defined in a profile
(e.g. [[hcard-profile]]) is the root class for that microformat. Problems:
* What about an XMDP that defines multiple microformats?
* What about a microformat that defines multiple possible root class names (e.g. [[hcalendar|hCalendar]] permits "vcalendar" or "vevent", [[hatom|hAtom]] permits "hfeed" or "hentry")?

=== linking to the XMDP ===

As hinted in the note on "when microformats may be in use", there are additional methods under discussion for linking to the XMDP in addition to the current method of using the profile attribute of the head element:
* Using <nowiki><link rel="profile" href="link to XMDP"/></nowiki>. This method can be used now and will be formalized in XHTML 2.
** A problem with this method is that it (still) requires access to the head element.
* Using <nowiki><a rel="profile" href="link to XMDP">powered by microformat xyz</a></nowiki> in the body of the document.
** As noted by a number of people, this approach has the added benefit of creating a viral marketing opportunity for the microformats used. For instance, developers could add badges saying they are using microformat xyz as suggested by the example.
** Blog authoring environments allow you to insert links at will, so this squarely <abbr title="avoids">obviates</abbr> the need to access the head element.

=== includes / aggregate profiles===

Methods for including one or more values, properties, or an entire XMDP into an other XMDP as a way of creating an aggregate profile that effectively contains definitions from multiple profiles would be quite useful. They would enable documents with microformats to simply refer to a single profile URL rather than a complete space separated set of all the profile URLs of the microformats that may be in use.

=== vocabulary aliasing ===

An XMDP document could be used to define a microformat profile that is nothing more than a simple dictionary mapping between an existing, non-standard set of HTML classes and the terms in a standard microformat profile. This would allow a publisher to support a given microformat by merely using the URI of a new profile document as the value of an individual document's head/profile attribute, rather than modifying the individual class values throughout each document to conform to an existing profile. Initial suggestion with use case description in this [http://microformats.org/discuss/mail/microformats-discuss/2005-October/001623.html microformats-discuss post]. Note (from [http://microformats.org/discuss/mail/microformats-discuss/2005-October/001633.html Kevin's response]) that HTML class attributes can contain multiple values, e.g. class="post hentry", so a publisher doesn't have to discard their existing class values to use those of a microformat.

=== subclassing / ontology addition ===
One may want to introduce a new property (or value) and base it on an existing property (or value). In this sample XMDP, the value "self" is defined, based on the value "me" from XFN 1.1:

<pre>
<nowiki>
<dl class="rel">
<dt id='self'><a href="http://www.gmpg.org/xfn/11#me" rev="extends">self</a></dt>
<dd>This is a pointer to me, it extends the "me" value of XFN</dd>
</dl>
</nowiki>
</pre>
There are two interesting pieces that have been added, a URL with an anchor to another XMDP profile and a rev attribute. The rev value in
this example is 'extends'. These means that the page this is refering too, is extended by the property SELF. So you could make an XMDP that
lists all the possible rev attributes, 'extends', 'inverse', 'equivalent', etc. Then you could 'alias' one microformat property to another.

A universal XMDP validator/parser/etc could extract data across two or more XMDP profiles and potentially reason between them. This could create a small ontology.

It is not clear if this idea actually has utility or is simply a solution looking for a problem.

== XMDP XML Schema ==
* [http://www.redantdesign.com/hcard/ XSD and XMDP for Microformats]
The link shows a bad example of creating XMDP from an XSD schema. The big question I guess is why?
Having XMDP defined in XSD should make it easier for machines to read Microformats, rules and strict data typing will allow Microformats to be validated when contained within an XML/XHTML document. If a document is using microformats with and XSD behind simple XPath queries can be used to harvest the information, this can then be rendered to straight XML for translation to RDF or other XML transport formats.

XSD behind XMDP also has distinct advantages for CMS authors, the XSD sitting behind xforms or sxforms to allow data entry into a CMS can be used to generate XMDP and valid Microformats when rendering content. This in theory should make it easier for CMS authors to develop a semantic core around data before exporting to XHTML + Microformats, RDF etc. and/or make data querying via web services a little more straightforward.
