Figure 8: Servers and their connectivity and capabilities | Open metadata may also capture the network endpoint(s) that the server is connected to and the host it is deployed to. The endpoint defines the parameters needed to connect to the server. It also features in the Connection model used by applications and tools to call the server. Thus through the endpoint entity it is possible to link the connection to the underlying server. Within the server are many capabilities. These range from full applications (see 0060 below) to security plugins to logging and encryption libraries. Different organizations and tools can choose the granularity in which the capabilities are captured in order to provide appropriate context to data assets and the decisions made around them. |
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 9 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 10 shows how applications relate to processes and the servers that host them

Networks and Gateways
The network model for open metadata is very simple, to allow hosts to be grouped into the networks they are connected to. This can show details such as where hosts are isolated in private networks, where the gateways onto the Internet.
