Connector Directories
Connector directories help to organize the connection definitions into logical groups to help people/tools locate the relevant connections. They are managed through the Connector Directory OMAS API.

Connection Linkage
The purpose of a connector is to access assets. In order for the connector to provide metadata about the asset it is accessing, there is a relationship between the connection and the asset. Notice the connection can only be associated with one asset - however assets may host smaller assets within them. In addition, some connectors are virtual connectors - by that we mean they implement an abstract to a business level asset and internally use one of more technical connectors as part of their implementation. The metadata repository can reflect these connection relationships using a VirtualConnection.

The base model introduced the concept of a data set. The data store definition shows how the data set relates to the server that it is hosted on.

Data Sets
Figure 6 5 extends the concept of DataSet to include virtual data sets - that is data sets built up from calling other data sets.

Applications provide business or management logic. They are often custom built but may also be brought as a package. They are deployed onto a server. Some applications are written to support specific processes. Figure 15 shows how applications relate to processes and the servers that host them
