Semantic MediaWiki

Semantic MediaWiki (SMW) is a free open-source extension to MediaWiki - the wiki software that powers Wikipedia - that helps to search organize tag browse evaluate and share the wiki's content. While traditional wikis contain only text which computers can neither understand nor evaluate SMW adds semantic annotations that allow a wiki to function as a collaborative database. Semantic MediaWiki introduces some additional markup into the wiki-text which allows users to add semantic annotations to the wiki. While this first appears to make things more complex it can also greatly simplify the structure of the wiki help users to find more information in less time and improve the overall quality and consistency of the wiki. Semantic MediaWiki was first released in 2005 and currently has over ten developers and is in use on hundreds of sites. In addition a large number of related extensions have been created that extend the ability to edit display and browse through the data stored by SMW: the term Semantic MediaWiki is sometimes used to refer to this entire family of extensions.
