All Implemented Interfaces:

DuplicateManagementInterface

public class StewardshipAction
extends Object
implements DuplicateManagementInterface

StewardshipAction provides the generic client-side interface for the Stewardship Action Open Metadata Access Service (OMAS). There are other clients that provide specialized methods for specific types of Asset. This client is initialized with the URL and name of the server that is running the Asset Owner OMAS. This server is responsible for locating and managing the asset owner's definitions exchanged with this client.
