Abstract:

To manipulate the heterogeneous and distributed data better in the data grid, a dataspace management framework for grid data is proposed based on in-depth research on grid technology.Combining technologies in dataspace management, such as data model iDM and query language iTrails, with the grid data access middleware OGSA-DAI, a grid dataspace management prototype system is built, in which tasks like data accessing, abstraction, indexing, services management and answer-query are implemented by the OGSA-DAI workflows.Experimental results show that it is feasible to apply a dataspace management mechanism to the grid environment.Dataspace meets the grid data management needs in that it hides the heterogeneity and distribution of grid data and can adapt to the dynamic characteristics of the grid.The proposed grid dataspace management provides a new method for grid data management.
