The document describes the Vienna History Wiki, a collaborative knowledge platform about the history of Vienna, Austria. Key points: - It was created by digitizing a printed 6-volume historical encyclopedia about Vienna from 1994-2004. - It uses Semantic MediaWiki, which allows storing facts inside wiki pages and exporting data as open data in RDF/JSON format. - External institutions contribute content and it has over 20,000 pages. Semantic queries can extract people, places, events and relationships from the data. - Challenges include making more content openly available as open government data and upgrading software. The goal is to expand content and users from city departments and citizens.
