扩展OGSA-DAI的数据集成框架及原型

Data Integration Framework and Prototype on OGSA-DAI Extension

提出了在OGSA-DAI数据服务模型的基础上以服务组合方式进行扩展的数据集成框架,利用OGSA-DAI扩展机制实现了支持3种集成操作的该框架原型。讨论了框架在应用中可能遇到的问题以及下一步的工作,将OGSA-DAI与科学数据网格数据访问服务(SDG-DAS)做了简要对比。

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.
