Wikidata is a free and open knowledge base that can be read and edited by both humans and machines.

Wikidata acts as central storage for the structured data of its Wikimedia sister projects including Wikipedia, Wikivoyage, Wiktionary, Wikisource, and others.

Wikidata also provides support to many other sites and services beyond just Wikimedia projects! The content of Wikidata is available under a free license, exported using standard formats, and can be interlinked to other open data sets on the linked data web.

Innovative applications and contributions from the Wikidata community

Featured WikiProject:
WikiProject COVID-19.

As the world combats the ongoing COVID-19 pandemic, Wikidata has been extremely useful in collecting and modelling useful information related to COVID-19, from relevant research articles and clinical trials, to epidemiological statistics of various regions, to lexemes for words and phrases commonly associated with the pandemic, and much more. A lot of work from WikiProject COVID-19 goes into creating and maintaining these items, bolstering Wikidata's role as a helpful open resource in the pandemic.
