About
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.
Problem
There is no unified, machine-readable, freely licensed knowledge base that can serve as a central store of structured facts across encyclopedic and reference projects.
For
researchers, developers, and knowledge contributors who need structured open data
How it works
Users and machines contribute structured data items with properties and values that are interlinked and exportable in standard open formats.
