Relformaide Dictionary:Semantic MediaWiki
Referata's sites, including the one you are just browsing now, use Semantic MediaWiki—an advanced version of the MediaWiki software that allows for better management of data than the regular counterpart. On semantic sites, users can store, organise and edit items with features such as properties, types and forms. Data can even be queried, thanks to the Special:Ask function.
The current installed version of Semantic MediaWiki (across Referata) is 18.104.22.168.
