Area 1 2 of the open metadata model covers the basic types of asset that need to be governed in order to make best use of them.  It builds out the core types of assets, extending from Asset, Infrastructure, DataSet and Process defined in 0010 Base Model.   Figure 1 shows the structure of the model files for area 1.  New classes and packages for this area are coloured blue.

Connectors and Connections

In area 0 we introduced the definitions for a server with an endpoint.  The server could host data and APIs.  The connection contains information to allow a client application or tool to connect to a particular endpoint.  The ConnectorType defines which connector implementation should be used to connect to the endpoint.  The Keystore holds authentication properties such as userId and password.  They are securely stored to protect the assets.

Connector Directories

Connector directories help to organize the connection definitions into logical groups to help people/tools locate the relevant connections.

Data Stores and Data Sets

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.  In addition, some data sets are virtual - that is they are build up from calling other data sets.  Figure 4 shows the data stores and virtual data sets linking to the data set.

Applications and Processes

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 x shows how applications relate to processes and the servers that host them
