Since 26 April, the metadata field “Provenio ID” has been added in Wikidata, uniquely identifying owners of books recorded in the Provenio database. The free, multilingual, secondary database Wikidata collects structured data to provide support for Wikipedia, Wikimedia Commons and other wikis of the Wikimedia movement, and to anyone in the world. Connecting Provenio and Wikidata will expand the circle of users and allow comparison with other databases, thereby also facilitating checking of data accuracy. Institutions such as the Bibliothèque nationale de France, British Museum and UNESCO have also worked with Wikidata.
