Issues with adding microformat mark-up to sites using [http://www.mediawiki.org/ MediaWiki] (such as this wiki, and [http://wikipedia.org Wikipedia]).

If you know of a solution, or work-around, please post it!

==URLs==
*Wiki mark-up such as <code><nowiki>[http://example.com sample text]</nowiki></code> (which displays as [http://example.com sample text]) cannot have a class="url" added to the output "<code>A</code>" element.
**Workaround (if display of the URL is acceptable): use <code><nowiki>http://example.com</nowiki></code> (which displays as http://example.com)
**Workaround (if display of the URL is not acceptable): ???
***Why not just use <code><nowiki>[http://example.com sample text]</nowiki></code>? --[[User:TiszaGergo|Tgr]][[User talk:TiszaGergo|talk]] / [[wikipedia:User:Tgr|home]] 06:16, 9 Aug 2007 (PDT)
****Returns a value of "sample text" [[User:AndyMabbett|Andy Mabbett]] 02:12, 10 Aug 2007 (PDT)

* The [http://www.mediawiki.org/wiki/Extension:ExtendAnchorTags ExtendAnchorTags] extension provides a work around using <xa></xa> tags, e.g.
<xa class="fn org" href="http://microformats.org/">microformats</xa>
will produce
<a fn class="fn org" href="http://microformats.org/>microformats</a> --[[User:JeffMcNeill|jeffmcneill]] 17:22, 20 Oct 2007 (PDT)

==Rel==
*Similarly, MediaWiki does not appear to support the use of the <code>rel</code> attribute on internal or external links.
** See [http://www.mediawiki.org/wiki/Extension:ExtendAnchorTags ExtendAnchorTags] extension --[[User:JeffMcNeill|jeffmcneill]] 17:22, 20 Oct 2007 (PDT)

==Tables==
*In the following code snippet (from an "[http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Infoboxes infobox]" table with an included [[hCard]]):

<code>
<pre>
<nowiki>
{| class="infobox vcard"
| class="fn org" | '''{{{name}}}'''
|-
{{#if: {{{address|}}} |
! Address
{{!}} {{{address}}}}}
|-
{{#if:{{{city|}}} |
! City
{{!}} {{{city|}}}}}
|-
{{#if:{{{country|}}} |
! Country
{{!}} {{{country|}}}}}
|-
{{#if:{{{latitude|}}} |
!
{{!}} <{{Coord|{{{latitude}}}|{{{longitude}}}|display=title}} }}
|}
</nowiki>
</pre>
</code>

:there is nowhere to hang the required <code>class="adr"</code>, such that it wraps the three relevant table rows, and no others.

*you can give a row a class (or any other valid HTML attribute) with <code><nowiki>{{!}} class="adr" {{!}} <span...</nowiki></code> --[[User:TiszaGergo|Tgr]][[User talk:TiszaGergo|talk]] / [[wikipedia:User:Tgr|home]] 06:16, 9 Aug 2007 (PDT)
**The need is not to apply a class to a single row, but (as stated) to apply it to (in this example) "the three relevant table rows, and no others". [[User:AndyMabbett|Andy Mabbett]] 02:14, 10 Aug 2007 (PDT)
***It seems this is a challenge with HTML tables and not necessarily MediaWiki? Please advise --[[User:JeffMcNeill|jeffmcneill]] 17:22, 20 Oct 2007 (PDT)
****Partly; but in HTML you can hang an intermediate class on <nowiki><tbody></nowiki>. [[User:AndyMabbett|Andy Mabbett]] 15:42, 19 Jan 2008 (PST)

==Abbr==
*MediaWiki supports the use of the <code>abbr</code> element, but this is disabled by some implementations (e.g. Wikipedia)
**See [[title-trigger]] for a proposed alternative to the [[abbr-design-pattern]], which would work on Wikipedia.
*** A mediawiki extension [http://www.mediawiki.org/wiki/Extension:EnableAbbrTags EnableAbbrTags] can support abbr by using a new xabbr command

==Dtend==

*The work-around for date-time pattern on Wikipedia (for example, birthdays in hCard) has been to use templates to output something like:

<pre>
<nowiki>
24 February 1993 (1993-02-24)
</nowiki>
</pre>

which degrades gracefully if CSS is not available. It is not acceptable to do so, to show the date advanced by one day for end-dates in hCalendar.

**See this [http://microformats.org/discuss/mail/microformats-discuss/2007-August/010449.html proposal to resolve exclusive end-date issue], for a proposal which would allow ''inclusive'' end dates to be marked up.

==XMDP==
*As with many CMSs, there is no facility for an editor to add an [[XMDP]] URI to (or in any other way to alter) the <code>head</code> element.

** Extensions can do this, working on it... --[[User:JeffMcNeill|jeffmcneill]] 17:22, 20 Oct 2007 (PDT)

==Address==

Address elements cannot be added to page content.

:<pre><nowiki><address class="vcard">The Microformat community</address></nowiki></pre>

displays as:

:<address class="vcard">The Microformat community</address>

*Not sure how this is a problem, which microformat uses this format? Markup within divs such as <pre><nowiki><div class="adr"></div></nowiki></pre> work fine. --[[User:JeffMcNeill|jeffmcneill]] 01:14, 21 Oct 2007 (PDT)

** [[hatom|hAtom]] uses <nowiki><address></nowiki>. [[User:AndyMabbett|Andy Mabbett]] 15:42, 19 Jan 2008 (PST)

=Mediawiki extension development=
*Are there any generic xml parsers/other extensions under development to provide support for some (most?) of the microformat needs? Is [http://ontoworld.org/wiki/Semantic_MediaWiki semantic mediawiki] a possible candidate for microformat support?
** It appears that semantic mediawiki is trying to do something different, namely OWL compliance. Based on the mediawiki [http://meta.wikimedia.org/wiki/Semantic_MediaWiki description of the semantic mediawiki project], ''hacks'' are to some extent discouraged (which to my mind is the orientation of Microformats). --[[User:JeffMcNeill|jeffmcneill]] 13:41, 18 Oct 2007 (PDT)

* Am working out the extensions needed to address this. --[[User:JeffMcNeill|jeffmcneill]] 17:22, 20 Oct 2007 (PDT)
