Abstract: A framework extending OGSA-DAI is proposed to make data integration by imposing service composition on OGSA-DAI data services. A prototype of the framework is implemented by taking advantage of extensibility of OGSA-DAI. Three kinds of integration operations are accomplished. Problems related to further applications of the framework, future work, and a brief comparison between OGSA-DAI and SDG-DAS (Data Access Service of Scientific Data Grid) are discussed.
