In the ten years of its existence, Wikidata has become an indispensable part of the Wiki project family. From the beginning, the development of the free knowledge database was an undertaking with big goals. Today, Wikidata is the largest collaboratively created collection of open data in the world — thanks to a community of over 12,000 active volunteers who continuously improve and add to data. 

On its tenth birthday, people around the world congratulate Wikidata and the community:

An international success story rooted in Germany

The Wikidata success story began in 2012 in Berlin, when a small group at Wikimedia Deutschland started developing the knowledge database. Now, ten years later, Wikidata has passed the milestone of 100 million data objects and has become an indispensable interface for numerous institutions and projects, first and foremost the online encyclopedia Wikipedia.

“Data can enrich our lives so much — if it is made available in an open, linkable and machine-readable form. No other place on the web does this as convincingly as Wikidata, because the knowledge database thrives on its unique international community of thousands of volunteers. Together, we want to continue to ensure over the next ten years that technology we all use every day is built on an open foundation that is accessible to everyone and to which everyone can contribute. This is the only way we can continue to provide access to free knowledge for all in the long term.”

Franziska Heine, Executive Director Wikimedia Deutschland
