All OMRS Connectors implement the same API. This API is called the OMRS Connector API. An OMRS Connector is an OCF Connector. This means it implements the OCF Connector API to provide access to an audit log plus the Connected Asset OMAS API to access metadata about the open metadata repository. In addition, the OMRS Connector provides access to the Metadata Collection API. This is shown in figure 1.

The Metadata Collection API allows searches, queries and maintenance of the metadata entities and relationship. It uses POJO style java objects to represent the metadata entities and relationships so that requests to the metadata repository are as efficient as possible without too much chattiness across the network if/when a metadata repository is remote from the OMRS Connector. Calls to the POJO style objects returned by the Metadata Collection API are local. Calls to the Metadata Collection API itself typically involve interactions with the metadata repository (or repositories) supporting the metadata collection.
Figure 2 shows the Metadata Collection API signature.
