<h1>Microformats Implementations and Implementors</h1>

This page lists the applications, plugins, sample code, services, tools as well as companies, developers and organizations which support microformats, along with the developers responsible for doing so that have chosen to be listed. This is only a partial list. If you know other companies implementing microformats, please add them and list their services and what specific microformats they support.

__TOC__

== Formats ==

Most microformat specifications have an "implementations" section, e.g.:
* [http://microformats.org/wiki/hcalendar#Implementations hCalendar], [http://microformats.org/wiki/hcard#Implementations hCard], [http://microformats.org/wiki/rel-tag#Implementations rel-tag], [http://microformats.org/wiki/vote-links#Implementations vote-links], [http://microformats.org/wiki/xoxo#Implementations XOXO] etc.

In addition, some microformat specifications have separate implementation pages:
* [[xfn-implementations]]

== Applications / Plugins / Services / Tools ==

This is an alphabetical listing of all applications, plugins (grouped with their app/tool), services and tools that implement microformats, along with the list of microformats that are supported, and the company and/or developers responsible for it.

As a user, the implementations listed below will automatically help you use microformats and help your data portability and interoperability with other apps and services.

Please help complete this list! If you know of additional apps/plugins/services/tools that support microformats, please add them!

Note: this section is only for listing specific ''implementations''. The list of ''implementors'' is in the [[implementations#Companies / Developers / Organizations|Companies / Developers / Organizations]] section below.

== Companies / Developers / Organizations ==

(Considering moving all of these to an [[implementors]] page of its own).

Thanks to all of the hardworking developers and innovative companies and organizations for supporting microformats.

This is an alphabetical listing of all companies, developers (by last name) and organizations who have built and shipped at least one implementation (see above for details of each implementation) that users can use.

Please help complete this list! If you have coded support for microformats and don't see your name, add it! If your company supports microformats in its applications, add it!

Note: please add direct links to specific applications, plugins, services, or tools to the list of [[implementations#Applications / Plugins / Services / Tools|Applications / Plugins / Services / Tools]] and then link to those from their implementor with a fragment identifier link, e.g. to link to the "Cork'd" wine review community:
* <nowiki>[[implementations#Cork'd|Cork'd]]</nowiki>
Similarly, for additional sites, put direct links to them in the [[implementations#Additional Sites|Additional Sites]] section and then link to them from their implementor with a fragment identifier link.

<h1> hAtom 0.1 </h1>

hAtom is a microformat for content that can be syndicated, primarily but not exclusively weblog postings. hAtom is based on a subset of the [http://www.atomenabled.org/ Atom] syndication format. hAtom is one of several [[microformats]] open standards.

== Introduction ==

hAtom is a [[microformat]] for identifying semantic information in weblog posts and practically any other place [http://www.atomenabled.org/ Atom] may be used, such as news articles. hAtom content is easily added to most blogs by simple modifications to the blog's template definitions.

== Semantic XHTML Design Principles ==
{{semantic-xhtml-design-principles}}

== Format ==
=== In General ===
The [http://atomenabled.org/developers/syndication/#person Atom Syndication Format] provides the conceptual basis for this microformat, with the following caveats:

* Atom provides a lot more functionality than we need for a "blog post" microformat, so we've taken the minimal number of elements needed.
* the "logical" model of hAtom is that of Atom. If there is a conflict, Atom should be taken as correct.
* the "physical" model of hAtom -- the actual writing of elements -- is a lot more varied than Atom provides for, due to the variety of ways weblogs are actually produced in the wild. The hAtom microformat provides a number of rules for "bridging the gap"

=== Schema ===
Schema elements are based on the Atom nomenclature and follow the microformat pattern of prefixing a unique identifier (in this case, '<code>h</code>') on the outermost container elements -- the Feed or Entry. The parts of this microformat are based on analysis of many weblog, bulletin board and media posts and can be read [[blog-post-brainstorming#Discovered_Elements]].

The hAtom schema consists of the following:

* hfeed ('''<code>hfeed</code>'''). optional.
* hentry ('''<code>hentry</code>''').
** '''<code>entry-title</code>'''. required. text.
** '''<code>entry-content</code>'''. optional (see field description). text.
** '''<code>entry-summary</code>'''. optional. text.
** '''<code>updated</code>'''. required using [[datetime-design-pattern]].
** '''<code>published</code>'''. optional using [[datetime-design-pattern]].
** '''<code>author</code>'''. required using '''[[hcard|hCard]]'''.
** '''<code>bookmark</code>''' (permalink). optional, using '''[[rel-bookmark]]'''.
** tags. optional. keywords or phrases, using '''[[rel-tag]]'''.

Some required elements have defaults if missing, see below.

=== Field and Element Details ===

===== Feed =====
* a Feed element is identified by the class name <code>hfeed</code>
* a Feed element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.1.1 Atom feed]
* the Feed element is optional and, if missing, is assumed to be the page
* hAtom documents MAY have multiple Feed elements

===== Feed Category =====
* a Feed Category element is identified by [[rel-tag]]
* a Feed MAY have a Feed Category
* a Feed Category element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.2 Atom category] inside a [http://www.atomenabled.org/developers/syndication/#optionalFeedElements feed]
* Feed Category elements MUST appear inside a Feed element but not inside an Entry element
* the [[rel-tag]] <code>href</code> encodes the atom <code>category:term</code>; the link text defines the atom <code>category:label</code>

===== Entry =====
* an Entry element is identified by class name <code>hentry</code>
* an Entry element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.1.2 Atom entry]
* any microformat content inside a <code><blockquote></code> or <code><q></code> element within the Entry is should not be considered part of the Entry.
: ''This allows quoting other microformated data without worry of corrupting the model''

===== Entry Category =====
* an Entry Category element is identified by [[rel-tag]]
* an Entry MAY have an Entry Category
* an Entry Category element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.2 Atom category] inside an [http://www.atomenabled.org/developers/syndication/#optionalEntryElements entry]
* the [[rel-tag]] <code>href</code> encodes the atom <code>category:term</code>; the link text defines the atom <code>category:label</code>

===== Entry Title =====
* an Entry Title element is identified by the class name <code>entry-title</code>
* an Entry SHOULD have an Entry Title
* an Entry Title element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.14 Atom entry title]
* if the Entry Title is missing, use
** the first <code><h#></code> element in the Entry, or
** the <code><title></code> of the page, if there is no enclosing Feed element, or
** assume it is the empty string

===== Entry Content =====
* an Entry Content element is identified by class name <code>entry-content</code>
* an Entry SHOULD have Entry Content
* an Entry Content element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#atomContent Atom content]
* an Entry MAY have 0 or more Entry Content elements. The "logical Entry Content" of an Entry is the concatenation, in order of appearance, of all the Entry Contents within the Entry
: ''Many weblogs split content into multiple sections with a "Read More" link and javascript tricks. This is also needed in cases where Entry Titles are coded inline and are considered part of the content.''
* if the Entry Content is missing, assume it is the empty string

===== Entry Summary =====
* an Entry Summary element is identified by class name <code>entry-summary</code>
* an Entry Summary element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.13 Atom summary]
* an Entry MAY have 0 or more Entry Summary elements. The "logical Entry Summary" of an Entry is the concatenation, in order of appearance, of all the Entry Summarys within the Entry

===== Entry Permalink =====
* an Entry Permalink element is identified by [[rel-bookmark]]
* an Entry SHOULD have an Entry Permalink
* an Entry Permalink element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.7 Atom link in an entry]

===== Entry Updated =====
* an Entry Updated element is identified by class name <code>updated</code>
* an Entry Updated element represents the concept of [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.15 Atom updated]
* an Entry SHOULD have an Entry Updated element
* use the [[datetime-design-pattern]] to encode the updated datetime
* if there is no Entry Updated element,
** use the Entry Published element, if present
** otherwise the page is invalid hAtom

===== Entry Published =====
* an Entry Published element is identified by the class name <code>published</code>
* an Entry Published element represents the concept of [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.9 Atom published]
* use the [[datetime-design-pattern]] to encode the published datetime

===== Entry Author =====
* an Entry Author element is represented by class name <code>author</code>
* an Entry Author element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.1 Atom author]
* an Entry Author element MUST be encoded in an [[hcard|hCard]]
* an Entry Author element SHOULD be encoded in an <code><address></code> element

<h1>Microformats Implementations and Implementors</h1>

This page lists the applications, plugins, sample code, services, tools as well as companies, developers and organizations which support microformats, along with the developers responsible for doing so that have chosen to be listed. This is only a partial list. If you know other companies implementing microformats, please add them and list their services and what specific microformats they support.

__TOC__

== Formats ==

Most microformat specifications have an "implementations" section, e.g.:
* [http://microformats.org/wiki/hcalendar#Implementations hCalendar], [http://microformats.org/wiki/hcard#Implementations hCard], [http://microformats.org/wiki/rel-tag#Implementations rel-tag], [http://microformats.org/wiki/vote-links#Implementations vote-links], [http://microformats.org/wiki/xoxo#Implementations XOXO] etc.

In addition, some microformat specifications have separate implementation pages:
* [[xfn-implementations]]

== Applications / Plugins / Services / Tools ==

This is an alphabetical listing of all applications, plugins (grouped with their app/tool), services and tools that implement microformats, along with the list of microformats that are supported, and the company and/or developers responsible for it.

As a user, the implementations listed below will automatically help you use microformats and help your data portability and interoperability with other apps and services.

Please help complete this list! If you know of additional apps/plugins/services/tools that support microformats, please add them!

Note: this section is only for listing specific ''implementations''. The list of ''implementors'' is in the [[implementations#Companies / Developers / Organizations|Companies / Developers / Organizations]] section below.

== Companies / Developers / Organizations ==

(Considering moving all of these to an [[implementors]] page of its own).

Thanks to all of the hardworking developers and innovative companies and organizations for supporting microformats.

This is an alphabetical listing of all companies, developers (by last name) and organizations who have built and shipped at least one implementation (see above for details of each implementation) that users can use.

Please help complete this list! If you have coded support for microformats and don't see your name, add it! If your company supports microformats in its applications, add it!

Note: please add direct links to specific applications, plugins, services, or tools to the list of [[implementations#Applications / Plugins / Services / Tools|Applications / Plugins / Services / Tools]] and then link to those from their implementor with a fragment identifier link, e.g. to link to the "Cork'd" wine review community:
* <nowiki>[[implementations#Cork'd|Cork'd]]</nowiki>
Similarly, for additional sites, put direct links to them in the [[implementations#Additional Sites|Additional Sites]] section and then link to them from their implementor with a fragment identifier link.

<h1> hAtom 0.1 </h1>

hAtom is a microformat for content that can be syndicated, primarily but not exclusively weblog postings. hAtom is based on a subset of the [http://www.atomenabled.org/ Atom] syndication format. hAtom is one of several [[microformats]] open standards.

== Introduction ==

hAtom is a [[microformat]] for identifying semantic information in weblog posts and practically any other place [http://www.atomenabled.org/ Atom] may be used, such as news articles. hAtom content is easily added to most blogs by simple modifications to the blog's template definitions.

== Semantic XHTML Design Principles ==

== Format ==
=== In General ===
The [http://atomenabled.org/developers/syndication/#person Atom Syndication Format] provides the conceptual basis for this microformat, with the following caveats:

* Atom provides a lot more functionality than we need for a "blog post" microformat, so we've taken the minimal number of elements needed.
* the "logical" model of hAtom is that of Atom. If there is a conflict, Atom should be taken as correct.
* the "physical" model of hAtom -- the actual writing of elements -- is a lot more varied than Atom provides for, due to the variety of ways weblogs are actually produced in the wild. The hAtom microformat provides a number of rules for "bridging the gap"

=== Schema ===
Schema elements are based on the Atom nomenclature and follow the microformat pattern of prefixing a unique identifier (in this case, '<code>h</code>') on the outermost container elements -- the Feed or Entry. The parts of this microformat are based on analysis of many weblog, bulletin board and media posts and can be read [[blog-post-brainstorming#Discovered_Elements]].

The hAtom schema consists of the following:

* hfeed ('''<code>hfeed</code>'''). optional.
* hentry ('''<code>hentry</code>''').
** '''<code>entry-title</code>'''. required. text.
** '''<code>entry-content</code>'''. optional (see field description). text.
** '''<code>entry-summary</code>'''. optional. text.
** '''<code>updated</code>'''. required using [[datetime-design-pattern]].
** '''<code>published</code>'''. optional using [[datetime-design-pattern]].
** '''<code>author</code>'''. required using '''[[hcard|hCard]]'''.
** '''<code>bookmark</code>''' (permalink). optional, using '''[[rel-bookmark]]'''.
** tags. optional. keywords or phrases, using '''[[rel-tag]]'''.

Some required elements have defaults if missing, see below.

=== Field and Element Details ===

===== Feed =====
* a Feed element is identified by the class name <code>hfeed</code>
* a Feed element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.1.1 Atom feed]
* the Feed element is optional and, if missing, is assumed to be the page
* hAtom documents MAY have multiple Feed elements

===== Feed Category =====
* a Feed Category element is identified by [[rel-tag]]
* a Feed MAY have a Feed Category
* a Feed Category element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.2 Atom category] inside a [http://www.atomenabled.org/developers/syndication/#optionalFeedElements feed]
* Feed Category elements MUST appear inside a Feed element but not inside an Entry element
* the [[rel-tag]] <code>href</code> encodes the atom <code>category:term</code>; the link text defines the atom <code>category:label</code>

===== Entry =====
* an Entry element is identified by class name <code>hentry</code>
* an Entry element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.1.2 Atom entry]
* any microformat content inside a <code><blockquote></code> or <code><q></code> element within the Entry is should not be considered part of the Entry.
: ''This allows quoting other microformated data without worry of corrupting the model''

===== Entry Category =====
* an Entry Category element is identified by [[rel-tag]]
* an Entry MAY have an Entry Category
* an Entry Category element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.2 Atom category] inside an [http://www.atomenabled.org/developers/syndication/#optionalEntryElements entry]
* the [[rel-tag]] <code>href</code> encodes the atom <code>category:term</code>; the link text defines the atom <code>category:label</code>

===== Entry Title =====
* an Entry Title element is identified by the class name <code>entry-title</code>
* an Entry SHOULD have an Entry Title
* an Entry Title element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.14 Atom entry title]
* if the Entry Title is missing, use
** the first <code><h#></code> element in the Entry, or
** the <code><title></code> of the page, if there is no enclosing Feed element, or
** assume it is the empty string

===== Entry Content =====
* an Entry Content element is identified by class name <code>entry-content</code>
* an Entry SHOULD have Entry Content
* an Entry Content element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#atomContent Atom content]
* an Entry MAY have 0 or more Entry Content elements. The "logical Entry Content" of an Entry is the concatenation, in order of appearance, of all the Entry Contents within the Entry
: ''Many weblogs split content into multiple sections with a "Read More" link and javascript tricks. This is also needed in cases where Entry Titles are coded inline and are considered part of the content.''
* if the Entry Content is missing, assume it is the empty string

===== Entry Summary =====
* an Entry Summary element is identified by class name <code>entry-summary</code>
* an Entry Summary element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.13 Atom summary]
* an Entry MAY have 0 or more Entry Summary elements. The "logical Entry Summary" of an Entry is the concatenation, in order of appearance, of all the Entry Summarys within the Entry

===== Entry Permalink =====
* an Entry Permalink element is identified by [[rel-bookmark]]
* an Entry SHOULD have an Entry Permalink
* an Entry Permalink element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.7 Atom link in an entry]
* if the Entry Permalink is missing, use the URI of the page; if the Entry has an "id" attribute, add that as a fragment to the page URI to distinguish individual entries

===== Entry Updated =====
* an Entry Updated element is identified by class name <code>updated</code>
* an Entry Updated element represents the concept of [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.15 Atom updated]
* an Entry SHOULD have an Entry Updated element
* use the [[datetime-design-pattern]] to encode the updated datetime
* if there is no Entry Updated element,
** use the Entry Published element, if present
** otherwise the page is invalid hAtom

===== Entry Published =====
* an Entry Published element is identified by the class name <code>published</code>
* an Entry Published element represents the concept of [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.9 Atom published]
* use the [[datetime-design-pattern]] to encode the published datetime

===== Entry Author =====
* an Entry Author element is represented by class name <code>author</code>
* an Entry Author element represents the concept of an [http://www.atomenabled.org/developers/syndication/atom-format-spec.php#rfc.section.4.2.1 Atom author]
* an Entry Author element MUST be encoded in an [[hcard|hCard]]
* an Entry Author element SHOULD be encoded in an <code><address></code> element
* an Entry SHOULD have at least one Entry Author element
* an Entry MAY have more than one Entry Author elements
* if the Entry Author is missing
** find the [[algorithm-nearest-in-parent|Nearest In Parent]] <code><address></code> element(s) with class name <code>author</code> and that is/are a valid [[hcard|hCard]]
** otherwise the entry is invalid hAtom
