OSOR mission

OSOR is a place where the Free and Open Source software community can come together to publish news, find out about events, find relevant open source software solutions and read about the use of Free and Open Source in public administrations across and beyond Europe. 

OSOR is a trustworthy observatory that provides FOSS expertise and information as well as serves as middle-ground to connect European Public Administrations with other relevant stakeholders. To reach this objective, OSOR promotes the use of Free and Open Source software and supports the community.
