Translate the Semantic MediaWiki extension

The Semantic MediaWiki (SMW) extension allows for managing structured data in your wiki and for querying that data to create dynamic representations: tables, timelines, maps, lists, etc.

The actual homepage of Semantic MediaWiki, including user documentation in multiple languages, is www.semantic-mediawiki.org. There are various other pages in the MediaWiki and Wikipedia space related to SMW, but the homepage is the most up-to-date source of information.

There are many "spinoff" extensions that require the presence of Semantic MediaWiki; see the category Semantic MediaWiki extensions for the full list (some of these extensions may be obsolete).

Download and installation
