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...
