| Since the OMAG Server does not have a metadata repository, all metadata is managed in other repositories and retrieved as required by OMRS:

Figure 2 shows the OMAG Server with both the Access Layer and a local metadata repository enabled. Now metadata from ABC is stored in its local OMAG Server's repository. This is blended with metadata from other repositories by OMRS. With a metadata repository in play, ABC can operate independently and connect into the open metadata repository cluster cohort and is therefore now a open metadata Native.

| The role of the repository proxy is to connect a proprietary metadata repository to the metadata highway and translate calls and messages between the XYZ proprietary formats and the open metadata formats.

Hence you see the OMRS message exchange between the Repository Proxy and other repositories in the clustercohort. |
