- An standard API called
getConnectedAssetPropertiesfor retrieving metadata. This API is defined by the OCF.
- An API for working with the resource itself. This interface is specialized for the type of resource and the use it is being put to.
It is configured using a connection
Various Egeria services provide specific interfaces for connectors to specific types of resources. For example, the Open Metadata Integration Services (OMIS) define the interfaces for integration-connectors used to exchange metadata between Egeria and third party technologies.
OCF connectors are not limited to representing Assets as they are physically implemented. An OCF connector can represent a simplified logical (virtual) asset, such as a data set, that is designed for the needs of a specific application or tool. This type of connector delegates the requests it receives to one or more physical data resources. It is called a virtual connector and us created using a virtual connection.
The connector catalog describes the connectors that are pre-built for the Egeria ecosystem.
The Egeria Developer Guide describes how to write your own connectors.
