Updated 01 Mar 2004 This paper explains how the Web Services Resource Framework is structured and how it operates.
The Web services architecture has been broadly accepted as a means of structuring interactions among distributed software services. Further standardization is now required to facilitate additional interoperability among services. One important area in which further standardization is required concerns interactions with stateful resources. In this paper, we address the constructs used to enable Web services to access state in a consistent and interoperable manner. We introduce the WS-Resource approach to declaring and implementing the association between a Web service and one or more named, typed state components. In this approach, we model state as stateful resources and codify the relationship between Web services and stateful resources in terms of the implied resource pattern, a set of conventions on Web services technologies, in particular WS-Addressing. When a stateful resource
participates in the implied resource pattern, we refer to it as a WS-Resource. We describe the means by which a WS-Resource is defined and associated with the description of a Web service interface. We also describe an approach for making the properties of a WS-Resource accessible through a Web service interface and for managing a WS-Resource’s lifetime.
