public class EnterpriseOMRSRepositoryConnector extends OMRSRepositoryConnector implements OMRSConnectorConsumer
EnterpriseOMRSRepositoryConnector supports federating calls to multiple metadata repositories. As a result, its OMRSMetadataInstanceStore (EnterpriseOMRSMetadataCollection) returns metadata from all repositories in the connected open metadata repository cohort(s).

An instance of the EnterpriseOMRSRepositoryConnector is created by each Open Metadata Access Service (OMAS) using the OCF ConnectorBroker. They use its metadata collection to retrieve and send the metadata they need.

Each EnterpriseOMRSRepositoryConnector instance needs to maintain an up to date list of OMRS Connectors to all the repositories in the connected open metadata repository cohort(s). It does by registering as an OMRSConnectorConsumer with the OMRSConnectorManager to be notified when connectors to new open metadata repositories are available.
