Wikimedia Deutschland – Gesellschaft zur Förderung Freien Wissens e. V. is a non-profit organisation based in Berlin, Germany. With about 150 employees and about 90.000 members, it is the oldest and largest of 40 independent chapters of the international Wikimedia movement. The most well-known Wikimedia project, the free online encyclopedia Wikipedia, is used by millions of people across the world every day and is continuously updated and improved by millions of users.
Wikimedia Deutschland furthers these ideals even beyond the free encyclopedia: It is our aim to establish and promote the creation, collection, and distribution of free knowledge in all parts of society. Our objective is to create a world in which the sum of all human knowledge is freely accessible for everyone. The main focus of our activities is the support of volunteers, the development of technology and software, and the cooperation with cultural and scientific institutions. Furthermore, we advocate on both the national and EU-level a legal framework which allows for free knowledge to become part of our everyday life.
All software we develop is Open Source, and we contribute back to various projects we use. Many of our components are published in a format that allows to re-use them beyond our own projects.
Wikimedia projects are open and collaborative projects in which anyone can participate. Software development is carried out by the Wikimedia Foundation, Wikimedia Germany and volunteer developers. The Wikidata and Wikibase projects are two of three primary projects worked on by Wikimedia Germany's software development department.
