Featuring Sovereign, Democratic Healthcare: Open-Source Medical Imaging Devices as a Proposal for Critical Infrastructure
Martin HÄUER, MLU Wittenberg University

Many public services, including healthcare, significantly depend on proprietary products and infrastructure. This tends to inflate the service costs enormously – to a simply unaffordable degree, especially in the global South. The Open Source Imaging Initiative (OSI²) has developed an MRI scanner – which allows everyone to use, study, share, and improve it – thereby counteracting the MRI oligopoly and opening up processes for clinical certification. This talk will give an overview of the OSI² initiative and outline the concept of democratic, sovereign technology for critical infrastructure.

APELL EU policy update: Open Tech Sovereignty for Europe!
Sebastian RAIBLE, APELL

2026 started with a bang: the EU Commission's consultation for a "European Open Digital Ecosystem Strategy" attracted more than 1600 submissions – making it one of the largest ever and underlining the demand for more Open Source in the EU! Can the EU Commission's proposals finally realise the potential of Open Source to deliver digital sovereignty?
In this APELL EU policy update, we will discuss current proposals like the Cloud and AI Development Act, the new Open Source Strategy and more, and find out what we can do to contribute to positive change.

Open Source for sovereignty. Fact or fiction?
Christian PATERSON, Open Up

A growing awareness is emerging amongst policymakers and, to a lesser extent, business leaders that we must reconsider our relationship with technology and the technology industry, which has created a comfortable but constraining dependency. For many, the rallying cry is "open source", which by its very nature promises greater digital independence. However, this call obscures several stark realities that clash sharply with the prevailing narrative.

AI Slop vs. Open Source: Why the Next Contribution Crisis Is Already Here
Philippe ENSARGUET, Orange

Open source was never just about code, it was about care, context, and trust. But AI-generated contributions are flooding projects with plausible-looking noise: slop PRs, hallucinated bug reports, vibe-coded patches no one understands. We are having multiple testimonials of examples where maintainers are overwhelmed. This talk argues we must redefine "contribution" beyond lines of code. In the age of AI slop, the real signal is human judgment, review rigor, and community stewardship. We don't need more code, we need more care.

Funding OpenSource products with the help of public transparency
Laurent SAVAETE, Ma Dada

Building on the Declaration of human rights of 1789, current Access to Information laws (in France, but in many other countries too) require public administrations to disclose (certain) documents when requested by citizens, companies and more.

After a short presentation of the legal context, this talk will show examples of documents that can be obtained to help FLOSS companies to find potential clients and more. Ma Dada (and its sibling platforms built on the OSS alaveteli app) will be demonstrated as a practical solution to navigate the minefield of Access to Information requests.

Mobilizon - a local solution for your local events
Alexandra CADET, Kauhuri

Today, most local events are published on massive platforms owned by tech giants. It’s time to shift direction — to build ethical, decentralized alternatives that are just as powerful and easy to use.
That’s exactly the mission of Mobilizon, initiated by Framasoft and supported by the European “Next Generation Internet” program.
On Mobilizon’s collaborative websites, users can create pages, groups, and events. But what truly sets it apart is its powerful interoperability: Mobilizon allows events to be imported and exported to any website, rather than locking users into a single space.

PrestaShop and calls for contributions: a structured collaboration
Paule MORIZOT, PrestaShop

In an open source project like PrestaShop, about 15% of contributions come from the community. However, contributions can take time to process, practices vary, and aligning contributions with the roadmap is not straightforward. To turn this into consistent impact, we introduced a "call for contributions” focused on roadmap-driven topics, informed by user feedback and technical readiness. This talk shares one year of results: how we select topics, support contributors, and improve throughput and quality. A practical case study for open source organizations handling high contribution volumes.

Decoding the EU Cloud Sovereignty Framework: A Strategic Roadmap for the Open Source Ecosystem
Emiel BROK, SUSE

As the EU accelerates its push for strategic autonomy, the EU Cloud Sovereignty Framework (v1.2.1, Oct 2025) has emerged as the definitive standard for digital services. But what does "sovereignty" actually mean in a technical and legal audit? This session explores the framework’s core components—the 8 Sovereignty Objectives (SOVs) and the 5 SEAL levels—to demonstrate why Open Source is not just a preference, but a mandatory foundation for reaching the highest levels of digital resilience and EU compliance.

Millions of learners earn credits yet never receive the credentials they deserve. The barriers are infrastructural: transfer audits are laborious, systems remain siloed, and the communication gap between institutions stubbornly persists.

This session will introduce the Learner Information Framework (LIF), an open source approach to portable, learner-centered records. We treat credential portability as a semantic and trust problem as much as a technical one. We will share emerging use cases, early patterns, and open questions as well as how AI can accelerate data mapping between systems.

Measuring the Stages of Open Source Adoption
Avi Press, Scarf

Traditional software analytics often uses the concept of a “funnel” to describe the user journey. Many people may be considering using a piece of software, some of those people will eventually try it, and some of those people will eventually use it regularly. In open source, quantifying this funnel is much harder, as the data signals in open source are very different from what a proprietary SaaS platform might see. In this talk, we describe a novel framework for describing and measuring the open source adoption lifecycle, and explore practical applications of this information.

The French Ministry of Education has provided LaForgeEdu a GitLab software forge, specifically intended for primary and secondary school teachers. However, this software forge was not designed with teacher’s practices in mind, and it’s interface and the terms it uses (eg: fork,commit, merge request) are difficult to apprehend. With the help of educational professionals, our aim is to lower the entry barrier for using software forges by providing a new teacher-centered interface called ForgeEditor. This paper presents the new ForgeEditor interface and two first user studies with 24 teachers.
