Featuring Sovereign, Democratic Healthcare: Open-Source Medical Imaging Devices as a Proposal for Critical Infrastructure

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. OSI² aims to provide open-source reference technology that can 1) serve as a product standard, 2) diversify supply chains (and eliminating vendor lock-ins) and 3) aid research e.g. via data comparability on fully characterized systems. This talk will give an overview of the initiative and outline the concept of democratic, sovereign technology for critical infrastructure.

Open Source for sovereignty. Fact or fiction?

To make sovereignty real rather than rhetorical, this talk will examine three realities that are too often overlooked: * Using open source does not make you "sovereign" if you do not master the technology. * Using open source does not make you "sovereign" if you do not retain independence in hosting. * Using open source does not make you "sovereign" if you do not support locally governed foundational ecosystems.

Open Source projects working together is key for European Digital Autonomy

In this talk we will show the power of collaboration between Open Source projects in the development and collaboration space and how this can change the narrative for European Digital Autonomy. We will show multiple collaborations providing key alternatives: - XWiki & OpenProject collaborating to deliver a full JIRA / Confluence alternative for development teams - The openDesk project bringing together 8 vendors to deliver a full Microsoft 365 alternative - Nextcloud, Collabora, XWiki, OpenProject partnering - CryptPad, nextGraph, BlockNote, Ironcalc and others working on a common research project (ELFA) on end to end encryption Open Source will strive if more projects work together to provide full offers. Also these collaborations puts the producers of Open Source software at the center of the offering, bringing funding to the actual producers of the code.

Beyond the black-box: architecting dynamic AI experiences for accountable value and contextual control

AI is fundamentally changing how customer-facing digital platforms behave. Modern digital experiences are no longer just deterministic flows built on content, rules and integrations. They increasingly rely on models, agents and external tools that reason, adapt and act at runtime. The result: behaviour emerges dynamically, not only at design time. This transition introduces a critical paradox: as AI capabilities expand, enterprise control diminishes, triggering new vulnerabilities in security, compliance and institutional trust. Without visibility into how AI features operate, customer-facing platforms quickly become black boxes: impossible to explain, hard to govern, and difficult to align with enterprise requirements around data usage, accountability and trust. In this session, we explore what transparent **glass-box AI** looks like in a customer-facing digital experience context: - how AI behaviour can be made observable, explainable and auditable - where architectural control points are required to retain ownership over data, decisions and outcomes - how risks such as bias, data leakage or unintended behaviour can be detected and actively steered - how humans stay in the loop, not as a last resort but as a design principle Rather than focusing on individual tools or models, the talk looks at **architecture, governance and responsibility**: what it takes to design AI-enabled digital experiences that organisations can understand, control and defend over time - especially in regulated, public or mission-critical environments. The session argues that digital sovereignty is not achieved through policy alone, but through **intentional architectural choices** that make transparency and control inherent properties of the system.

An independent browser to raise the bar on security, resiliency and strategic autonomy

At the crossroads of strategic autonomy, open source, supply chain security, and day-to-day high-attack-surface component, we only find one element: the browser. Firefox’ browser engine, Gecko, is to date the only cross-platform not based on Blink which is controlled by Google. To be able to sustain our long term goals for the community and our mission, we think it is time to build a branch of Mozilla that enables the ecosystem to leverage a product built specifically with enterprise deployment in mind. We aim at building a new product that ensures a new funding source for the engine, while addressing the challenges required by enterprises and governments: supply chain security, resiliency, support, all this with increased security features that can only be deployed with an infrastructure backend. To that effect, we are building strategic partnerships that are helping us learn how to operate this new version of Firefox both on-prem and in SecNumCloud certified clouds in order for users to have increased control over their data and the associated services typically needed by a modern browser. . In this talk, we propose to start with a quick state of affairs for the architecture and services behind a modern browser, explore the landscape of the enterprise-focused browser ecosystem, and describe how Mozilla is building something strong for the users, that can benefit their security and increase their sovereignty. Finally, we provide some feedback on the challenges we face, going from customers needs, raising security, improving supply chain control, the legal compliance and infrastructure deployment, and how that works in the open.

PrestaShop and calls for contributions: a structured collaboration

In an open source project like PrestaShop, 15% of contributions come from the community. However, results are mixed: contributions go unprocessed, practices lack standardization, internal teams are overloaded, and integration into the product roadmap is complex. To address these challenges, we launched a new approach: a call for contributions. This approach relies on a clear roadmap defined by the product teams, guided by user feedback and necessary technical developments. These calls enable us to concentrate efforts on priority topics that are better documented, technically ready, and easier to integrate. This presentation provides feedback on the past year, including concrete results and the goals of this new approach. We will explore how topics are selected, how we support contributors, and how this approach has accelerated collaboration and the quality of contributions. It offers a practical case study for any open source organization managing large volumes of contributions.

Decoding the EU Cloud Sovereignty Framework: A Strategic Roadmap for the Open Source Ecosystem

The European Commission’s Cloud Sovereignty Framework represents a major shift from general security compliance to specific "sovereignty-by-design" requirements. Born from initiatives like Gaia-X and CIGREF, it provides a quantitative method to assess the independence of digital services from non-EU actors and proprietary lock-in. In this talk, Emiel Brok will break down the framework for the OW2 community, focusing on two critical assessment pillars: The Sovereignty Effective Assurance Level (SEAL): Mapping the requirements from SEAL-0 (No Sovereignty) to SEAL-4 (Full Digital Sovereignty), and explaining which technical safeguards are required at each stage. The 8 Sovereignty Objectives (SOVs): A deep dive into Legal, Operational, and Supply Chain Sovereignty, and how they impact the procurement and development of cloud-native stacks. We will specifically address how the "EU First" policy is reshaping the digital landscape and why open-source technology is the only viable path to achieving a high "Sovereignty Score." The session will conclude with a call to action for European providers and developers to align their roadmaps with these standards to ensure long-term operational resilience and market relevance in a regulated Europe.

From Telco Cloud to Sovereign AI Factory: Enabling AI Inference at the 5G Edge

As Europe pursues technological sovereignty in digital services, the transformation of traditional telecommunications infrastructure into distributed AI Factories offers a vital path toward achieving true strategic autonomy. This value proposition shifts the focus from simple network-oriented edge locations to a decentralized model where AI inference is executed locally on trusted infrastructure rather than in hyperscalers’ centralized clouds. By leveraging a European open source orchestration layer to unify the cloud-edge continuum, telco operators can reclaim control over their data and resources while providing the benefits inherent to the 5G edge, such as reduced latency and local processing that keeps data closer to end-users and IoT devices. This approach facilitates the efficient coexistence of critical network functions and localized AI inference tasks on shared, vendor-neutral platforms, ensuring that sensitive data remains within its jurisdiction throughout its lifecycle. The presentation introduces a practical architectural blueprint for Telco AI Factories, detailing a reference framework and key operational considerations for managing distributed inference at scale. It highlights how open source technologies form the backbone of resilient, interoperable, and resource-efficient sovereign AI ecosystems.

Regaining Control of Virtualization with Proxmox: Solutions and Outlook

n a context of increasing dependency on proprietary solutions such as VMware—often associated with high costs, limited transparency, and poor reversibility—many organizations are now looking to regain control over their IT infrastructure. Proxmox VE has emerged as a strong open-source, unified, and mature alternative for building a sovereign, resilient, and sustainable virtualization platform. It is worth highlighting the strategic importance of these challenges across several dimensions: Technology: An open-source solution built on proven virtualization components, compatible with standard protocols, without compromising on technological scope. Financial: Clear, transparent pricing with no hidden fees, proportional to the chosen level of support. Sovereignty: A European vendor, helping reduce exposure to U.S. extraterritorial legislation. Beyond these strategic drivers, the solution’s appeal is also grounded in solid technical foundations: A consistent platform that brings virtualization, storage, networking, and backup into a single interface. No dependency on specific hardware. Operations that are both straightforward and comprehensive, supported by a robust RESTful API. Proxmox VE version 9 represents a major milestone, introducing multiple significant improvements, including: Optimized live migrations to simplify switching virtualization environments. Advanced GPU sharing (mediated devices) and SR-IOV support. SAN storage support. Major progress in migration paths from proprietary environments. True autonomy also requires resilience. Proxmox Backup Server enables an integrated and efficient backup strategy without relying on third-party solutions that may be subject to the same legal and operational constraints. The presentation will conclude with the expected outlook for Proxmox VE 9, highlighting community momentum and anticipated evolutions: improved GPU management for AI workloads, extended clustering across geographically distributed zones, security hardening, and finally practical advice and real-world feedback for successfully transitioning to a new virtualization environment.

Alternatives to Active Directory

Large organizations managing Linux desktop fleets face a critical gap: while Microsoft Active Directory provides centralized policy management (GPO) for Windows, no equivalent open-source solution exists for Linux desktops. Active Directory is not a single product but a bundle of services. Most have mature open-source equivalents — OpenLDAP for directories, MIT Kerberos for authentication, GLPI for inventory. However, some of them, especially GPO functionality remains unaddressed for Linux desktops. Existing configuration management tools (Ansible, Puppet, SaltStack) target server infrastructure, lack native dconf/GNOME support, and don't provide the offline capability, drift detection, or OU-based targeting that enterprise desktop management requires. Our approach was: decompose AD functionality, identify existing open-source components, and develop only what is missing. The gap analysis reveals that ~90% of AD services are already covered. The remaining 10% _(centralized policy enforcement for GNOME desktops (dconf settings, files, services, packages, printers, mounts)_ is the core problem to solve. This leads to a focused development scope: a policy engine with targeted appliers, a lightweight pull-based agent with offline cache, and a unified admin console federating existing tools via REST APIs. Rather than building a monolithic AD replacement, the solution orchestrates proven open-source components and fills only the critical gap.

DatWeb: Building Custom Scientific Tools with Peer-to-Peer Data

**Science is undergoing a shift toward openness**—but the tooling for working with data still lags behind. Researchers struggle with reproducibility, fragmented datasets, and collaboration workflows that don’t reflect how modern science actually happens. **DatWeb** is an open-source project built on **peer-to-peer** principles that brings **version-controlled data** and **custom tooling** directly to the web. Inspired by the original **Dat protocol**, it enables scientists, educators, and open data communities to build and share their own data-driven applications with just a few lines of code. Instead of relying on centralized platforms, DatWeb allows teams to: - **share evolving datasets with built-in versioning** - **create reproducible workflows** - **build lightweight, domain-specific tools tailored to their research** In this talk, we’ll explore how **decentralized data infrastructure** can support open science practices such as reproducibility, collaboration across institutions, and long-term data access. Through live examples, we’ll demonstrate how DatWeb is being used to prototype custom tools for scientific and educational use cases—without requiring large engineering teams or complex infrastructure. Whether you're a **researcher, developer, or newcomer to open source**, this session will show how peer-to-peer technologies can unlock a new generation of open, composable tools for science and education.

Measuring the Stages of Open Source Adoption

Understanding user journeys in open source is a unique challenge. Unlike proprietary SaaS platforms with access to precise user metrics, open source projects rely on a mix of indirect signals such as downloads, contributions, and community interactions. How can we define and measure the open source adoption lifecycle with these fragmented data points? In this talk, I will present a new framework designed specifically for open source projects to quantify user adoption stages, awareness, trial, regular usage, and contribution. We’ll also demonstrate how this framework can be applied to real-world scenarios to improve onboarding, enhance retention, and foster deeper community engagement. Attendees will gain actionable insights to transform data into strategies that grow their projects sustainably.

Sustaining Open Source in/for Science: From Project to Ecosystem

Open Science is not just a policy shift—it is an infrastructure transformation. At its core is open source research software, the digital backbone enabling reproducibility, collaboration, and discovery. Yet despite its critical role, much of this software remains fragile: underfunded, undervalued, and often abandoned. Drawing on findings from a U.S. National Science Foundation, Alfred P. Sloan Foundation, and Chan Zuckerberg Initiative sponsored workshop, this session explores what it will take to sustain open source as the foundation of modern research ([report here]([url](https://sr.ithaka.org/wp-content/uploads/2026/03/SR-Brief-Sustaining-Open-Source-Software-in-the-Research-Enterprise.03.25.26.pdf))) The workshop, hosted by [Apereo Foundation]([url](https://www.apereo.org/)) and [Ithaka S+R]([url](https://sr.ithaka.org/)), brought together leaders across academia, industry, and open source software communities to examine why research software struggles to persist—and how we can change that. We’ll unpack key challenges identified by participants, including the lack of institutional incentives to treat software as scholarship, the difficulty of tracking impact and adoption, fragmented ownership models, and the cultural gap between researchers and open source practitioners. We’ll also highlight emerging solutions: funding software as infrastructure rather than short-term projects, integrating students into open source ecosystems as a workforce pipeline, establishing campus-wide coordination through OSPOs and/or foundations, and developing standards for discoverability, attribution, and trust. More broadly, this session reframes sustainability as a multi-dimensional problem—spanning motivation, infrastructure, archival practices, and community. Attendees will leave with a clearer understanding of how open source practices—from version control to community governance—can be adapted to meet the needs of science at scale. Whether you’re building research tools, shaping institutional policy, or contributing to open science communities, this talk offers a roadmap for turning open source from a byproduct of research into a durable, shared foundation for it.
