About

Semantic MediaWiki (SMW) is a free, open-source ex­ten­sion to MediaWiki – the wiki soft­ware that pow­ers Wikipedia – that lets you store and query data with­in the wiki's pages. 
Semantic MediaWiki is also a full-fledged frame­work, in con­junc­tion with many spin­off ex­ten­sions, that can turn a wiki into a pow­er­ful and flex­i­ble know­ledge manage­ment sys­tem. All data cre­ated with­in Semantic MediaWiki can easi­ly be ex­port­ed or pub­lish­ed via the Semantic Web, al­low­ing other sys­tems to use this data seam­less­ly. 

By supporting SMW financially, you are contributing to the development and maintenance of the software as well as for other activities (like marketing and community building).
