MediaWiki's extension framework makes it very easy to create your own
extension to parse tags on a page to do interesting things. Here's what
I've done on my own:
- AmCharts — Mediawiki extension to allow you
to use AmCharts for chart input and output.
- SiteGraph — Extension to graph a
MediaWiki pages.
- UnihanTag — This provides access
to the Unihan database for Unicode.
