Check usage and version matrix.

Semantic MediaWiki (SMW) is an extension 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 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 a large number of "spinoff" extensions that require the presence of Semantic MediaWiki; see the category Semantic MediaWiki extensions for the full list (some of these extensions are obsolete).

Download and Installation

The respective instructions are located on the help page about installing Semantic MediaWiki.

Please refer to the extension's homepage for information on how to obtain this extension. Using the extension distributor of mediawiki.org for this purpose is strongly discouraged.

Make sure to set "Compatibility Mode"

If your wiki has also Cargo or Wikibase installed you need add the following to your "LocalSettings.php" file to have Semantic MediaWiki work:

$smwgEnabledCompatibilityMode = true;
