This document discusses the use of Semantic MediaWiki as a tool for co-creation. It describes how the Vienna History Wiki uses Semantic MediaWiki to digitize a printed encyclopedia, store facts within wiki pages, and export data as open data. Key features highlighted include structured data entry, faceted search, querying data, and automatically generating pages from the stored information. The document argues that Semantic MediaWiki provides an open-source, easy to use tool for collaborative knowledge management and sharing information as open data.
