Translate the Semantic MediaWiki extension

TheSemantic MediaWiki (SMW) extension allows you to manage structured data in your wiki and query that data to create dynamic representations, such as tables, timelines, maps, lists, etc.

The actual homepage of Semantic MediaWiki, including user documentation in multiple languages, iswww.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.

Many "spinoff" extensions require the presence of Semantic MediaWiki; see the categorySemantic MediaWiki extensions for the complete list (some of these extensions may be obsolete).

The instructions are on thehelp page about installing Semantic MediaWiki.
