Term: Service Expression Definition

---

A core e-Framework term referring to a machine-processible definition or specification of the interface to a service expression and the semantics of the service expression. It defines the message formats, datatypes, transport protocols, and transport serialisation formats that should be used between the requestor service implementation and the provider service implementation. Formats, datatypes, protocols, etc., should be based on defined standards and specifications. The service expression definition represents an agreement governing the mechanics of interacting with the service expression.
