The mapping between a third party metadata repository and the open metadata protocols in a Repository Proxy is implemented in two connectors:
- An OMRS Repository Connector
- An OMRS Event Mapper Connector
They are configured as follows.
The OMAG Server can act as a proxy to a vendor's repository. This is done by adding the connection for the repository proxy as the local repository.
POST {{serverURLRoot}}/open-metadata/admin-services/users/{adminUserId}/servers/{serverName}/local-repository/proxy-details?connectorProvider={fullyQualifiedJavaClassName}
Any open metadata repository that supports its own API needs an event mapper to ensure the Open Metadata Repository Services (OMRS) is notified when metadata is added to the repository without going through the open metadata APIs.
The event mapper is a connector that listens for proprietary events from the repository and converts them into calls to the OMRS. The OMRS then distributes this new metadata.
POST {serverURLRoot}/open-metadata/admin-services/users/{adminUserId}/servers/{serverName/local-repository/event-mapper-details?connectorProvider={fullyQualifiedJavaClassName}&eventSource={resourceName}
For example, to enable the IBM Information Governance Catalog event mapper,
POST the following (where igc.hostname.somewhere.com is the hostname of the
domain (services) tier of the environment, and 59092 is the port on which
its Kafka bus can be accessed):
POST {serverURLRoot}/open-metadata/admin-services/users/{adminUserId}/servers/{serverName}/local-repository/event-mapper-details?connectorProvider=org.odpi.openmetadata.adapters.repositoryservices.igc.eventmapper.IGCOMRSRepositoryEventMapperProvider&eventSource=igc.hostname.somewhere.com:59092
