Research on the specification framework and key technology of WS-DAI
网络服务下的数据访问与集成规范架构

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.
