FactGrid

FactGrid is a wiki-based knowledge base for historical researchers. It is operated as a joint venture between the University of Erfurt, Wikimedia Deutschland, and the German National Library. Like this wiki and Wikidata, FactGrid runs on MediaWiki with the Wikibase extension. Its criteria for inclusion are as lax as possible in order to support original research.
