As web technologies advance and model-based engineering (MBE) gains momentum, the need for lightweight, web-based graphical modeling tools has never been greater. The Eclipse Sirius project addresses this challenge with Sirius Web , a modern, low-code framework for building domain-specific modeling tools directly in the browser. A standout example of what’s possible with Sirius Web is SysON , a gr...

The SysON 2025.4.0 release brings major improvements: user library management, enhanced graphical capabilities with support for new object types, better textual import and export and many other updates - all while staying aligned with SysMLv2 Beta 2.4. Libraries Management: Reuse Made Simple Many UX Improvements Better Textual Import Improved Export to Text   Libraries Management: Reuse Made Simpl...

At Obeo, we are actively exploring how artificial intelligence can be combined with model-based systems engineering (MBSE) to enhance engineering efficiency and accessibility, while maintaining the rigor required for the development of complex and critical systems. We currently see two main areas where AI brings clear value: AI as a modeling assistant : AI can support engineers in their daily mode...

Last December, we presented a prototype of a custom tool for the space industry, showcasing how SysON can be used to create user-friendly modeling environments aligned with specific methodologies. This tool was developed as part of EasyMOD , a collaborative project supported by the European Space Agency (ESA), Airbus Defence and Space, Airbus Commercial Aircraft, HDGroup, and the French Government...

We are pleased to announce that the 2025.4 release of  Sirius Web is now available! You can find the complete list of fixes, improvements and new features is available in the changelog . In this blog post, we’ll take a closer look at some of the major improvements and new features included in this release. Library Support: Reuse and Share Models Across Projects Explorer: Duplicate Elements Easily ...

With each SysON new release, we strive to make SysML V2 modeling more seamless and efficient. The SysON 2025.2.0 release introduces several enhancements that simplify modeling, improve usability, and ensure better compliance with the SysML v2 specification. A Smoother Modeling Experience More Control Over Your Models Enhanced Compliance and Model Traceability Enhanced Diagram Export Diagrams Impro...

  Thanks to the Eclipse Foundation , and as a member of the Open Regulatory Compliance Working Group (ORC WG), I had the opportunity to participate in a panel at an exciting event on the Cyber Resilience Act (CRA), organized as a prelude to FOSDEM! We explored the impact of this regulation on the open source ecosystem, its legal implications, and the challenges we face together. It was an incredib...
