Abstract: The Open Grid Services Architecture (OGSA) defines the Grid service concept using principles from both the Grid computing and Web Services models. OGSA lets developers integrate resources and services across distributed, heterogeneous, and dynamic environments. This paper explores OGSA and Grid service concepts by discussing both current implementations and recently proposed standards, such as the Web Services Resource Framework (WSRF). To show the benefits of the OGSA approach, we present the Grid Data Integration System (GDIS), an OGSA based architecture for data integration on Grids. Data integration on Grids is a challenging issue due to the large scale, dynamic, autonomous and distributed nature of data resources. GDIS exploits OGSA services to support federation, analysis, and processing of data from different distributed sources.
