Structured Data on Wikimedia Commons is a collaboration between developers and the communities of Wikimedia Commons, Wikidata, Wikipedia, and sister projects.

The developer team consists of staff from both the Wikimedia Foundation and Wikimedia Deutschland. Community developers (tool developers, bot operators, developers at partner organizations) can also play a large role in this project. All the developed features are designed, created, tested and improved in close collaboration with the community of active contributors to Commons, Wikidata, Wikipedia, and sister projects. And we also warmly welcome active feedback from cultural institutions (GLAMs)!
