1. A data processing method comprising: receiving a request for a service interface description of a service from a client at a server, the service being implemented via a first service endpoint at the server, the first service endpoint being associated with a first service endpoint interface description; employing a given set of correlations for determination of service endpoints correlated with the first service endpoint with respect to the service, each of the correlated service endpoints being associated with a service endpoint interface description; generating the service interface description by aggregating the first service endpoint interface description with the service endpoint interface descriptions of the correlated service endpoints; and providing the generated service interface description by the server to the client.
