| 摘 要： | Web服务通知(WS-Notification)和Web服务资源框架(WS-Resource Framework，简称WSRF)规范提供可扩展的发布／预定通知模式和用Web服务为有状态资源(Statefu Resource)建模的能力。本文首先介绍了OGSI和WSRF的关系，WSRF可以简单地看作是OGS11．0规范中的概念和接口的重写。WSRF通过Web服务资源(WS-Resource)方法来为有状态资源建模，通过WS-Resource方法来说明、执行Web服务和一个或多个指定类型的状态组件间的关系，阐述了通过Web服务接口来设置WS-Resource的属性和生命周期的方法，还讨论了预定／发布模式的通知机制是如何建立在WSRF基础上的，最后对WSRF和WS-Notmcation进行了简单总结并讨论了它的未来研究方向。

| Abstract: | The WS-Notification specification and the WS-Resource Framework (WSRF) provide a scalable publish/ subscribe (pub/sub) messaging model and the ability to model stateful resources using Web services. In this paper, the relationhip between OGSI and the WSRF is introduced first. WSRF can be viewed as a straightforward re factoring of the concepts and interfaces developed in the OGSI version 1.0 specification. WSRF tries to model Stateful Re- sources with Web Services Resource approach to declaring and implementing the association between a Web service and one or more named typed state components. An approach is described for making the properties of a WS-Re- source accessible through its Web service interface and for managing a WS-Resource's lifetime. The discussion on how a pub/sub notification mechanism (WS-Notification) can be built on top of the WS Resource framework is also given. Finally,this paper also presents a summary of WSRF and WS-Notification briefly and a simple discussion on the future research. |
