Great question Oscar!
You’re pointing out a known flaw in many (most?) openEHR modelling tools; they don’t expose all relevant reference model attributes to the modeller. I think the RM “participations” would be a great way of representing MDT attendees, but unfortunately for now you can’t explicitly include this in your template. Depending on your implementation tools you may still be able to use it though, for example we can make limited use of it in our DIPS tools.
This issue of lacking RM exposure in tools has been mentioned in several other topics:
- ACTION ‘reason’ exposed in tools? - Implementation / Tools - openEHR
- INSTRUCTION_DETAILS attributes missing in ACTION Archetypes in CKM - Tool Support / CKM - openEHR
In another topic, @mar.perezcolman proposed using an interim CLUSTER to mitigate some limitations of the “participation” model: Additional ‘Participations’ metadata item - Specifications / RM - openEHR
