OSOR is a ISA project of the European Commission.

serves as a place where the EU 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.

The underlying philosophy is to promote collaboration, sharing and digital development by providing the following main services:


Publishes information, experiences and best practices around the open source software in public administrations. Additionally, the Knowledge Centre gives access to key resources such as studies and guidelines. 


Promotes open source software through community engagement activities such as participation in events, social media, and production and publication of content.


Provides information and offers ad-hoc legal support services on the licensing of open source software solutions in cooperation with the EUPL collection.

The OSOR community is characterised by three main stakeholder groups: national and local public administrations, private sector, and citizens such as academics and open source software enthusiasts. Each group can contribute to the further adoption of open source and benefit from the OSOR initiative by reading up-to-date news and in-depth case studies that are posted on a regular basis.
