What is Semantic MediaWiki

Semantic MediaWiki (SMW) is a free and open-source extension to MediaWiki. SMW lets you store and query data within your wiki's pages. It turns your wiki into a flexible collaborative knowledge base for your knowledge management. Thousands of wikis use Semantic MediaWiki. From large enterprises that use SMW for their internal knowledge management needs to public institutions that use SMW to publish their datasets. View testimonials.

Semantic MediaWiki is an alternative to Wikibase .
