How does SysON implement the Project and Model Elements?

[TheNightFox-1]

Hi everyone,

I really like how SysON handles the Project and Model elements, especially since these concepts are not explicitly defined in SysML v2. It’s a very elegant solution.

However, I’m still trying to understand how exactly this is implemented. In particular, I noticed that these elements do not appear in the textual notation when it is downloaded.

Could you please clarify how SysON implements the Project and Model elements and how this relates to the SysML v2 specification?

Hello,

Thank you for using SysON and for your kind words!

The projects/models elements are not related to the SysMLv2 specification, they come from Sirius the project on which SysON is built upon.

Nevertheless, we mapped our concept of project to the SysMLv2 project concept from the standard REST APIs (see https://doc.mbse-syson.org/syson/v2026.1.0/developer-guide/api/api.html for more details).

Regards,
