Wikidata is a free, collaborative, multilingual, secondary knowledge base, collecting structured data to provide support for Wikipedia, Wikimedia Commons, the other wikis of the Wikimedia movement, and to anyone in the world.

Our goal is to match people and places from Queens Name Explorer to their corresponding Wikidata items, creating new Wikidata items when they do not yet exist.

As we match, edit, and create Wikidata items for people and places, it will power a dynamic list that includes links to corresponding Wikipedia articles and OpenStreetMap features.
