Help:SMW - Number of downloads
One of the common ways to obtain Semantic MediaWiki is to download it's file releases from SourceForge. This page keeps the cumulated number of downloads of Semantic MediaWiki within each listed month. They show that Semantic MediaWiki is gradually picking up popularity since it's first release on September 30, 2005. Please note that the number of clones from the Git repository since May 2012 or checkouts from the SVN repository until April 2012 are not included in the numbers shown here. Since the switch to Composer as the preferred method of installing Semantic MediaWiki in January 2014 these statistics are not longer maintained.
