Open Source MBSE at Scale: From Industry-Proven Tools to Web-Native SysML v2
Cedric Brun, CEO of Obeo, and Asma Charfi, from CEA, look back on 15 years of open-source ecosystem development and share their vision for the next generation of Model-Based Systems Engineering (MBSE) tools.
Context
Summary
This joint presentation explored how open-source MBSE technologies have evolved over the past 15 years — from Eclipse-based industrial tools like Capella, Papyrus, and Sirius, to new web-native environments supporting SysML v2 and agent-assisted engineering.
Key messages included:
- The power of open ecosystems for accelerating innovation in education, research, and industry.
- Lessons learned from large-scale industrial adoption of MBSE tools.
- The emergence of next-generation modeling environments — collaborative, extensible, and AI-augmented, bridging the gap between domain experts and software engineers.
The talk sparked lively discussions and a strong interest from the IEEE community regarding the convergence of open-source platforms and upcoming SysML v2 tooling.
Highlights
- 15 years of open collaboration across the Eclipse ecosystem — from early Papyrus and Capella foundations to today’s vibrant MBSE community.
- Industry-proven tools at scale, including Capella and its extensions (Team, Cloud, and Publication), showcasing how open-source can sustain mission-critical engineering.
- A live proof of concept illustrating “Obeo Enterprise for SysON,” combining SysML v2 with Arcadia semantics and an AI agent assisting the creation of a logical architecture for the X-Wing spacecraft.
- A forward-looking perspective on the transition to web-native, cloud-enabled, and AI-augmented modeling platforms built for openness and collaboration.
