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...

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...

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...
