Implementing the SysML v2 standard is a massive engineering challenge. With this 2025.12 release , the SysON team continues to strengthen the foundations. While we haven't reached the end of the road yet, we are hitting key milestones to make modeling more predictable and robust.   Expanded functionality for diagrams Flexible Displays : Objects could be displayed in different ways on the same diag...

SysON 2025.10 is here, and it feels like a breath of fresh air. Fully aligned with the SysML v2 2025-07 release , it brings a wave of thoughtful improvements that make modeling smoother, clearer, and simply more pleasant. Open your project, try the new touches, and enjoy.   Modeling that keeps evolving Better Control of your views A smoother modeling experience Textual import and libraries Integra...

The  European Space Agency (ESA) is undergoing a progressive transition from  traditional paper-based engineering processes to a unified, fully digital platform based on the  Model Based Systems Engineering (MBSE) principles. As part of this transformation, I am currently leading the IDEF project to develop an Integrated, web-based Digital Engineering Framework, with the SysON tool at its core. Th...

SysML v2 is reshaping the way systems engineers approach modeling, offering a modernized syntax and semantics designed to improve precision, tool interoperability, and developer experience. Yet, as with SysML v1, the standard itself remains intentionally neutral: it defines a notation, not a methodology. For teams working on the architecture of complex systems, whether in aerospace, transportation...

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...

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...

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...
