I am ok, if we decide to use UUID in common model to represent service-instance-id , but we would need to define additional field in common model to represent service Model ID , which will be mapped from

SDC.UUID

AAI.model-version-id

SDNC.service.model-UUID

It seems to me important to include service MODEL Id attribute in the common model, as we will be setting the rules which will be relying on service model meta-data

Thanks
