The Eclipse SysON project provides an open-source web-based tooling to edit SysML v2 models. It includes a set of editors (graphical, textual, form-based, etc.) enabling users to build the various parts of system models. Capitalizing on the capabilities of the Sirius Web platform, SysON offers a user-friendly interface, facilitating seamless model creation, modification, and visualization.
Furthermore, Eclipse SysON is the core of the SysMLv2 model editing feature of Papyrus and seamlessly enables co-design of SysMLv2 models alongside Eclipse Capella.
