Semantic MediaWiki

General Information
Semantic MediaWiki is an open-source extension to MediaWiki that allows you to store semantic data in pages - database - like data that can be queried and aggregated. This is done through special markup tags; it is recommended that these tags be stored in templates.

For much more information about Semantic MediaWiki, including a full guide for both users and administrators, see the Semantic MediaWiki homepage.
