Hello CW Dillon,

The magic involves changing core MediaWiki code. <abbr> and <acronym> tags are blacklisted by default. You have to "unblacklist" them in Sanitizer.php, and the rest is just template magic.

In Sanitizer.php, Sanitizer::removeHTMLtags() function, add 'abbr' and 'acronym' elements to the $htmlpairs array.

Then, in the same file, in Sanitizer::setupAttributeWhitelist(), find the two "abbr" and "acronym" commented lines and replace them with:

'abbr' => $common, 'acronym' => $common,

After that, you will be allowed to use abbr and acronym tags in your pages. Like this:

<abbr title="eXtensible Markup Language">XML</abbr>

I used some template magic to make this less tedious. There are templates for each abbreviation and acronym, like {{XML}}, that expands to, for example:

{{abbr|XML|eXtensible Markup Language}}

and {{abbr}} and {{acronym}} templates that expand to, respectively:

<abbr title="{{{2}}}">{{{1}}}</abbr>

<acronym title="{{{2}}}">{{{1}}}</acronym>

Regards, Juliano.

Juliano, I like your approach to blogging in MW, but I'm even more curious about your abbreviations tags, for example in the post about Mozilla Bookmarks to Wiki (21 July 2006). I looked at the templates and tags, but saw no extension controlling this on your Version page. Can you say how this is done? I don't like the heavy java in the ToolTips extension. Your approach is more like what I'm looking for.
