hello, apologies if this is the wrong list to post/discuss this (i read through the mailing lists wiki page and this one seems to be the most suitable). after not finding the functionality (acronym tooltip + glossary link) that i was looking for in mediawiki (including extensions) i would like to add an extension that supports the below: 1. provide a tag to markup an acronym/abbreviation: when moused over, a tooltip will be displayed (using the 'title' html attribute) that provides the expansion of the acronym. 2. additionally, if a glossary page is specified then the text is linked to the relevant section of that page. alternatively, if a page with the acronym as its title is present, the text is linked to that page. with regards to this idea, i have a set of questions: 1. is this already done/possible? assuming, not: 2. is it possible to use wiki markup rather than an HTML tag: {{gl|XML}} or some such, rather than <gl>XML</gl> would i do this using templates plus the extension? 3. the acronym list needs to be stored somewhere, either implicitly in the glossary page or externally. one possible location is the MySQL DB. is modifying the DB (for extension dev) frowned upon? comment: feature item #2 (glossary/page link) perhaps is better left to regular wiki markup (since it can already be done that way)... any thoughts or comments appreciated! --ravi
