Building Sustainable Open Source Ecosystems for an Interoperable Europe

How can we create a sustainable open source ecosystem to support the new intergovernmental

cooperation framework in the Interoperable Europe Act?

Workshop within the framework of the Open Source Workshops for Computing and Sustainability event

Albert Borschette Conference Center, Brussels: 02 December 2022

Workshop time: 10:00-11:30 CET | Room 1A


Workshop Description

With the recent adoption of the interoperability regulation proposal - the Interoperable Europe Act - in mind, the European Commission’s Open Source Observatory (OSOR) is bringing together stakeholders to discuss it in the context of the earlier recommendations on the software, culture and ecosystems of open source provided by the Expert Group for the Interoperability of European Public Services.

While the Act focuses on reinforcing cross-border interoperability and cooperation between the Member States and the European Commission (the co-owners of the proposed governance structure), the nature of interoperability means that the collaboration will be multi-dimensional and the provisions of the Act will also impact open source communities, projects, and companies. In particular, Article 4: Share and reuse of interoperability solutions between public sector bodies, institutions and agencies of the union and Article 8: Interoperable Europe portal, which include references to code sharing and open source licencing, might influence the open source environment both in the public and private sector.

DG DIGIT D2 of the European Commission will open the session with a presentation on the Interoperable Europe Act, with particular focus on the areas where collaboration with open source stakeholders is needed. The panellists and participants are invited to discuss the key topic of building sustainable ecosystems around public sector use of open source and open standards for interoperable public services. We will also debate the Act’s ambitions in view of the recommendations of the Expert Group regarding support for open source software and providing the catalogue of open source solutions for the public sector.
