Proof of Concept
The EU OS projects develops a proof of concept (PoC) to explain IT decision makers and the open source community better the vision of the project. The proof of concept also helps determining rough edges and missing pieces and brings them to the attention of the upstream projects, so that they can be addressed early on.
As of now, EU OS does not benefit from funding and the PoC is a pure community effort. The work happens continously on the EU OS Gitlab, in the Matrix channel #eu-os-dev:kde.org and at some face-to-face meetings/hackathons:
- Hack Days June 2025 in Paris, see also DINUM press release (French only). Details: #31
- November 2025 Online Sprint with weekly meetings coordinated via the Matrix channel #eu-os-dev:kde.org. Details: commit d78ca67a
Conferences and Discussions
- Luxembourg Open Source Conference 2025: "EU OS, an operative system for the public sector" (slides, programme)
- Annual Privacy Forum 2025: panel discussion "Panel Session I: Digital Sovereignty" (no slides, programme)
- Informal Meeting with the Commission’s own IT department: "EU OS for European Commission Staff: Promises and Status Q4 2025" (slides)
Tutorial to Setup the PoC in your own Environment
For the Proof of Concept, EU OS proposes an architecture and an implementation to address the requirements laid down on the Spec page, so that IT decision makers and interested system administrators can learn and study. Note that for the implementation original software development is avoided as much as possible. The value of this setup is to gather documentation in one central place and to propose a tested integration of various components that is not so common as of 2025.
