Working with connectors
The specialized interface to work with the specific contents of the asset. For example, if the connector was for data stored in a relational database, this interface would probably follow the Java Database Connectivity (JDBC) specification. The documentation for this interface is found with the specific connector. These are the connectors supported by ODPi Egeria with links to the documentation:
basic-file-connector provides connector to read a file. It has no special knowledge of the format.
csv-file-connector provides connector to read files that have a CSV tabular format.
data-folder-connector provides connector to read a data set that is made up of many files stored within a data folder.
A generalized interface to extract all of the open metadata known about the asset. This is referred to as the connected asset properties. This interface is documented here.
An application creates a connector using the Asset Consumer OMAS client. When an Asset is cataloged in the open metadata repository, there is a Connection object linked to it. This defines all of the properties required to create the connector.
Once the connector is created, an application may use it to retrieve the content of the asset and the connected asset properties.
When the application has finished with the connector, it should call
disconnect() to release any resources
that the connector may be holding.
