Hi all,

we are currently working on the SCOT (Service Concept for Tendering) use case. In this context, we have a new requirement: rolling stock vehicles should be able to reference categories from the timetable. The idea is to indicate which categories a vehicle can be used for. Our current approach is to introduce such references, i.e., a collection of references to collections.

Since the category is currently located in the timetable subschema, and we want to avoid introducing circular dependencies between subschemas, this would require moving the category to the common subschema.

Our first question is whether you see any issues with this approach.

If we proceed, we would also need a clear and descriptive name for the moved category, in particular as the meaning cannot be derived as easily from the context anymore after moving. At the moment, we are considering "trainCategory" or "serviceCategory." Do you have any suggestions?

Your feedback is appreciated.

Best regards,
Milan
