<entry-title>Profile URIs</entry-title>
{{TOC-right}}
== Introduction ==
In [[hcalendar-issues]], it is ACCEPTED that each microformat should have a profile URI, like [http://gmpg.org/xfn/11 the XFN profile].
==Known URIs==
This section lists known profile URIs for microformats. To promote cacheability and recognisability of profile URIs, authors {{should}} avoid minting new URIs for existing microformats, and {{should}} re-use existing well-known profile URIs.
=== Combined Profile ===
The following URL covers all non-draft Microformats as of March 2008, except XMDP. You can mix and match it with other XMDP profiles for new/draft microformats.

=== Other Interesting Profile URIs ===
=== (X)HTML 5 / XHTML 2 ===
An alternative method is provided for people using markup languages which do not support <code><nowiki><head profile></nowiki></code>. Add <code>rel="profile"</code> to either a visible link (<code><nowiki><a></nowiki></code>) or hidden link (<code><nowiki><link></nowiki></code>).


* [http://purl.org/uF/pattern-data-class/1 Experimental data-* class pattern]
Example:
* [http://purl.org/stuff/hdoap/profile hDOAP (posh format)] &para;&dagger;
<source lang=html4strict><p>This page uses

</source>


== How to link to a profile URI ==
=== Atom 1.0 ===


=== <code><nowiki><head profile></nowiki></code> ===
(This is a draft idea being implemented in the XML::Atom::Microformats Perl parsing module.)


This is the original method of linking to profile URIs and is currently supported by the greatest number of tools. This is valid in HTML 4 and XHTML 1.x, but is not valid in Atom (as Atom has no <code><nowiki><head></nowiki></code> element) or current drafts of HTML 5 and XHTML 2.
To indicate that an Atom <code>&lt;content></code> element contains a Microformat, give the entry a <code>&lt;link rel="profile"></code> link to the relevant profile URI. You can indicate that ''all'' entries within a feed contain a particular microformat by including <code>&lt;link rel="profile"></code> on the root Atom <code>&lt;feed></code> element.  


Example:
Example:
<pre><nowiki><html>
<source lang=xml>
   <head profile="http://example.com/profile1 http://example.net/profile2">
<feed>
     ...</nowiki></pre>
  <title>Example Feed</title>
 
   <link rel="profile" href="http://ufs.cc/x/hcard" />
=== <code>rel="profile"</code> ===
  <entry>
    <title>Example Entry Containing hCard</title>
     <content type="text/html">...</content>
  </entry>
  <entry>
    <title>Example Entry Containing hCard and hCalendar</title>
    <content type="text/html">...</content>
    <link rel="profile" href="http://ufs.cc/x/hcalendar" />

</feed>
</source>


An alternative method is provided for people using markup languages which do not support <code><nowiki><head profile></nowiki></code>. Add <code>rel="profile"</code> to either a visible link (<code><nowiki><a></nowiki></code>) or hidden link (<code><nowiki><link></nowiki></code>).

For [[cms]]'s there  is:

How to link to a profile URI

HTML 4.x / XHTML 1.x

  <head profile="http://gmpg.org/xfn/11 http://microformats.org/profile/hcard">

(X)HTML 5 / XHTML 2

An alternative method is provided for people using markup languages which do not support <head profile>. Add rel="profile" to either a visible link (<a>) or hidden link (<link>).

Example: 

<p>This page uses
<a rel="profile" href="http://gmpg.org/xfn/11">XFN 1.1</a>!</p>

Atom 1.0

(This is a draft idea being implemented in the XML::Atom::Microformats Perl parsing module.)

To indicate that an Atom <content> element contains a Microformat, give the entry a <link rel="profile"> link to the relevant profile URI. You can indicate that all entries within a feed contain a particular microformat by including <link rel="profile"> on the root Atom <feed> element.

Example: 

<feed>
  <title>Example Feed</title>
  <link rel="profile" href="http://ufs.cc/x/hcard" />
  <entry>
    <title>Example Entry Containing hCard</title>
    <content type="text/html">...</content>
  </entry>
  <entry>
    <title>Example Entry Containing hCard and hCalendar</title>
    <content type="text/html">...</content>
    <link rel="profile" href="http://ufs.cc/x/hcalendar" />
  </entry>
</feed>

Content Management Systems

For cms's there is:

Implementations

GRDDL

Tools that support GRDDL use profiles to parse microformats.

Cognition

In "strict mode", Swignition (formerly called Cognition) refuses to parse any microformats where the profile URI has not been explicitly declared on the page. (It will however, still parse microformats for which there exists no profile URI!)

HTML::Microformats

HTML::Microformats uses profile URIs to toggle support for individual microformats.

Issues

When this section gets too big, move it to profile-uris-issues Some issues include:

Validator warning

Due to inconsistent wording of the HTML specs, HTMLTidy (and other tools?) give "Warning: <head> escaping malformed URI reference" when more than one profile is used, e.g. 

<head profile="http://microformats.org/profile/hcard http://microformats.org/profile/hcalendar">

W3C HTML validator has very poor validation of attributes and is technically unable to check this case. The HTML DTD however defines profile attribute as %URI (it's an alias for CDATA), same as <a href> attribute.

Experimental URIs

The following includes URIs to external experimental XMDPs, and should only be used for testing purposes.

Experimental Combined Profile

The following URL covers all non-draft Microformats as of March 2008, except XMDP. You can mix and match it with other XMDP profiles for new/draft microformats.

Essentially dead

  • (copied from grddl): As someone who was an early proponent of GRDDL, I'd state that as of 2015-03, it is essentially dead along with any profile-based metadata systems including xmdp. The GRDDL specification relies on the profile attribute which has been deprecated in HTML5. Evidence to that effect: the W3C GRDDL reference service is offline, no attempt has been made to build an alternative that is HTML5-compliant (such as implementing html5-profile). It is probably time to call time of death on GRDDL and profile-uris. —Tom Morris 16:52, 16 March 2015 (UTC)
