This whitepaper introduces the WS-Resource framework specifications that express the relationship between stateful resources and Web services.
The WS-Resource construct has been proposed as a means of expressing the relationship between stateful resources and Web services. We introduce here the WS-Resource framework, a set of proposed Web services specifications that define a rendering of the WS-Resource approach in terms of specific message exchanges and related XML definitions. These specifications allow the programmer to declare and implement the association between a Web service and one or more identified, typed state components called WS-Resources. They describe the means by which the type of a WS-Resource is defined and associated with a Web service description. They also describe how the state of a WS-Resource is made accessible through a Web service interface, and define related mechanisms concerned with resource grouping and addressing. This paper provides an architectural overview of the WS-Resource framework. It motivates, introduces, and summarizes the interrelationships among five separate specification documents that provide the normative definition of the framework: WS-ResourceProperties, WS-ResourceLifetime, WS-RenewableReferences, WS-ServiceGroup, and WS-BaseFaults. We also describe how the WS-Resource framework can support a specification concerned with event notification, WS-Notification.

- The specifications related to the WS-Resource Framework are:
WS-Notification,
WS-ResourceProperties,
WS-ResourceLifetime.
- The family of WS-Notification specifications include: WS-BaseNotification, WS-BrokeredNotification, and WS-Topics.
- Stateful resource management is important to the maintenance of the current state of any Grid computing system.
- The Open Grid Services Architecture shows how Grid computing can take advantage
of Web services and build a service-oriented architecture for the Grid model.
- The Web services Grid zone keeps regular coverage of new developments in Grid technology.
