Wikidata
A free and open knowledge base readable and editable by humans and machines.

Wikidata is a free, open knowledge base that serves as central structured data storage for Wikimedia projects like Wikipedia, Wikivoyage, and Wiktionary. It can be read and edited by both humans and machines, and its content is available under a free license in standard formats. Wikidata also supports many third-party sites and services through linked open data.
Users and machines contribute structured data items with properties and values that are interlinked and exportable in standard open formats.
