Described is a Web Services Application Protocol (WSAP) comprising a SOAP-based protocol that defines a web service application model based on a set of common message operations. WSAP provides a foundation for defining web services in terms of how they interact with each other. In WSAP, the behaviors of a service are each provided with an individual port, (e.g., URI), whereby the service's behaviors may be interacted with directly. WSAP also defines shared semantics for operations that identify what a message is, what the processing of message is, and how it affects the state/behavior of the receiver. The ordering of messages also provides context to what is occurring. As a result of the known characteristics of the operations and the ordering, an intermediary can process exchanged messages to add value to communications. A SOAP processing model defines composing multiple web services to run in parallel or sequentially.
