Large Scale Data Management on Grids

We explore the status, challenges and opportunities in providing a resource center focused on large scale data management on the EGEE Grid, in the context of the emerging Spanish e-Science Network. The application to bulky and relatively flat datasets in High Energy Physics is mature and in daily production. Transferring this methodology to other application fields is still ongoing, posing challenges to the Grid Infrastructure, the Resource Centers and the Grid middleware and even to the human aspects of collaborative science.
