Inside the OMRS are 4 major groups of components: Enterprise Repository Services, Administration Services, Cohort Services and Local Repository Services
Image Modified Figure 2: Component Overview (level 1) | - Enterprise Repository Services provides a virtual metadata repository by combining the content of multiple open metadata repositories and delivering this metadata through a single API and event topic. The Enterprise Repository Services provide the enterprise access metadata support for the OMASs.
- Administration Services drive the initialization of the OMRS at server start up plus access to the OMRS's internal status. It relies on the OMAG Server to supply it with the configuration information to initialize the connectors it should use and connector with other open metadata servers.
