Wikimedia Deutschland does not just provide support to volunteers who want to share their knowledge with the world through the Wikimedia projects. We also take care of making continuous improvements to the technical infrastructure behind Wikipedia and its sister projects. This includes, for example, working on the software that runs all Wikimedia projects. We also work closely with volunteers to develop technical projects that allow Wikipedia to be further developed and to spread Free Knowledge. A large project, on which we are working hand in hand with an international community, is the collaboratively maintained Free Knowledge database Wikidata. This was started at Wikimedia Deutschland in Berlin in 2012 and has since been expanded and further developed under our leadership. Our work in the field of software development aims to do that which the many thousands of Wikimedia contributors have dedicated themselves: giving more people more access to more knowledge.
