OpenDLibG: Extending OpenDLib by Exploiting a gLite Grid Infrastructure

摘要

This paper illustrates how an existing digital library system, OpenDLib, has been extended in order to make it able to exploit the storage and processing capability offered by a gLite Grid infrastructure. Thanks to this extension OpenDLib is now able to handle a much wider class of documents than in its original version and, consequently, it can serve a larger class of application domains. In particular, OpenDLib can manage documents that require huge storage capabilities, like particular types of images, videos, and 3D objects, and also create them on-demand as the result of a computational intensive elaboration on a dynamic set of data, although performed with a cheap investment in terms of computing resource.
