The release of Sirius-Web 2025-04 provides a way to publish Studio as Libraries. (see https://blog.obeosoft.com/sirius-web-2025-4) We need a such feature to be able to share models as Libraries between the UML Projects. The feature seems activated in Papyrus-Studio (with CTRL-K), but not yet availble in Papyrus models. In addition, once the feature will be connected, we will need to update Papyrus-Web documentation :-) .
