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:

MediaWiki extension for profile URIs

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:

what domain to use? Candidates include:
- microformats.org
- www.w3.org
- gmpg.org
- One proposal is: use www.w3.org, following W3C namespace policy.
- Use microformats.org and GMPG profile URIs - Tantek 10:17, 6 August 2009 (UTC)
what about versioning? How to keep in sync with the wiki and test materials?
- As to versioning, change the profile whenever the underlying spec changes significantly (within some reasonable latency, say, a couple weeks or a month). For example: an hCard Profile at w3.org, and discussion: an hCard profile that seems to work with GRDDL.
what profile URI to use for combinations, such as hcard and hcalendar?
- note HTML4.01 states "that one or more meta data profiles, [are] separated by white space"; though it's simpler for authors if they can just use one profile URI.
- e.g. use <head profile="http://microformats.org/profile/hcard http://microformats.org/profile/hcalendar">
More profiles are needed.
- Like which ones??

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.

Other Interesting Profile URIs

Discussion

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)
- The fact that I've just pruned two of the three entries in profile-uri-examples-in-wild is rather telling. —Tom Morris 16:56, 16 March 2015 (UTC)

-== 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.
