0201 Connectors and Connections

In Area 0 we introduced the definitions for a server with an endpoint (model 0040). The server could host data and APIs. The Open Connector Framework (OCF) provides client java classes called connectors to enable an application, tool or engine to access this data and other deployed functions.

A Connection metadata entity contains the configuration information to allow the OCF's Connector Broker to select and configure the appropriate 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 securedProperties holds authentication properties such as userId and password. They are securely stored to protect the assets. If they are missing then the security credentials of the current user are used with the connection.

By default, connector implementations are assume to support the OCF. However, many vendor platforms have their own connector frameworks. The ConnectorCategory allows equivalent connector types from different connector frameworks to be gathered together so that the connector type from a connection can be swapped for an equivalent connector type for the locally supported connector framework.

The picture below shows how the connector category can be used to navigate to a different connector type implementation.

The next picture shows the ConnectorTypeDirectory can be used to organize the ConnectorCategories.
