The Web Services Resource Framework defines a family of specifications for accessing stateful resources using Web services. It includes the WS-ResourceProperties, WS-ResourceLifetime, WS-BaseFaults, and WS-ServiceGroup specifications. The motivation for these new specifications is that while Web service implementations typically do not maintain state information during their interactions, their interfaces must frequently allow for the manipulation of state, that is, data values that persist across and evolve as a result of Web service interactions. For example, an online airline reservation system must maintain state concerning flight status, reservations made by specific customers, and the system itself: its current location, load, and performance. Web service interfaces that allow requestors to query flight status, make reservations, change reservation status, and manage the reservation system must necessarily provide access to this state. In the Web Services Resource Framework we model state as stateful resources and codify the relationship between Web services in terms of an implied resource pattern.
