AAS Registries for Submodel Templates and Instances #62

Closed StenGruener closed 2 years ago

StenGruener commented 2 years ago

Q: Is there a way to determine submodel kind (i.e., Template or Instance) from a Registry without loading the actual submodel from via AAS-repository API? A: Currently submodel kind can not be retrieved using Registry-API. We propose to maintain a dedicated registry for submodel Templates.

@BirgitBoss: can this discussion be checked within the UAG?

BirgitBoss commented 2 years ago

I will put it to the agenda next year. But I agree: you should not mix AAS instances (or Submodel instances) and Submodel Templates in a single registry/repository. The requirements are very different.

Cleaned up text proposal for now: Q: Is it possible to determine submodel kind (i.e., Template or Instance) from a Registry without loading the actual submodel from via AAS-repository API? A: Currently submodel kind can not be retrieved using Registry-API. This issue will be addressed by standardization working groups. In the meantime, we propose to maintain a dedicated registry for submodel templates within the AAS-infrastructure. Submodel templates can be part of a "singleton-AAS" with a dedicated asset ID used to collect those.
