Open Metadata Governance Servers Documentation

A governance server is a specialized OMAG Server. It is designed to host connectors that manage metadata in different technologies.

Each type of governance server is paired with an Open Metadata Access Service (OMAS) that supports the same metadata types that the governance server is managing in the third party technology. The governance servers each have a specific subsystem that contains its services.

The table below shows the different types of governance servers and the OMAS they are paired with. Some of the governance servers are daemons - that means they have no external API and are driven entirely by changes in metadata and the IT landscape.

Further information

Each governance server has its own documentation (follow the links above). In addition, there is an overview design document for developing a new governance server.
