Using SysON for Space Applications at ESA

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...

Extending SysON to Support the Arcadia Method: A First Experiment

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...

Sirius Web & SysON: Building Next-Generation Modeling Tools for Complex Engineering

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...
