The Governance of the Service Inventory using the Service Repository and Registry is a complex multiphase cyclic process, covering a service's lifecycle aspects—from the cradle to the grave.

The utility for the synchronization of Registry and Repository to compensate tModels' limitations and expand the runtime Discoverability options
An API and simple UIs to handle and control all the artifacts in Registry and Repository
