Web Services Metadata Exchange

Web services use metadata to describe what other endpoints need to know to interact with them. For example, WS-Policy describes the capabilities, requirements, and general characteristics of Web services; WSDL describes abstract message operations, concrete network protocols, and endpoint addresses used by Web services; XML Schema describes the structure and contents of XML-based messages received and sent by Web services.
