Provided is a Web Services Response Template (WSRT) that addresses the problems of efficiency and robustness to change in Web Services response by allowing a requestor to explicitly specify, in a response template what information is to be returned by the request. A requestor of a web service gets just the information it needs; different requestors of the same operation may get different information; and a responder sends the requestor only what is asked for so there is no problem when new information becomes available. WSRTs are specifically designed to allow the type of control needed in program-to-program (P2P) communication, while being very efficiently and simply processed by a web service. Thus, WSRTs address difficulties that arise in typical distributed, P2P communication without adding much overhead or complexity to either a service requester or a service provider. The efficiency and flexibility afforded by WSRTs is essential to emerging enterprise architectures based on SOA (Service Oriented Architecture).
