摘　　要：在开放网格服务体系下的数据访问与集成(OGSA-DAI)项目和网络服务下的集成资源框架(WSRF)规范的背景下,介绍了网络服务下的数据访问与集成(WS-DAI)提出的一组W eb Service数据访问与集成的通用数据接口规范,能扩展支持各种类型的数据资源。分析了WS-DAI的规范架构,详细研究了核心抽象模型并给出应用实例。最后讨论了此规范与WSRF之间的映射。With the background of OGSA-DAI and WSRF, a Web Service data access and integration specification for a collection of generic data interfaces presented by WS-DAI was introduced. The specification can be extended to support specific kind of data resources. The framework of the specification was analyzed. The paper also studied on the core of the abstract model in detail and an application example was presented. Finally the mapping to WSRF was discussed.
