| Our team, as technical coordinators and Grid technology experts, is developing a generic middleware platform, based on our proposed service-oriented architecture, RDLS (Rich Data Location Services) , which enables efficient content management in Grid environments. Our design introduces concepts from Peer-to-Peer and distributed computing in order to provide a scalable and reliable infrastructure for storage, search and retrieval of annotated multimedia content. | ||||||||

| < < | To ensure fast media lookups in the distributed repositories of a Virtual Organization, our system incorporates a multidimensional indexing scheme, which serves the need for supporting both point and range queries over a set of meta-data attributes. | |||||||
| > > | To ensure fast media lookups in the distributed repositories of a Virtual Organization, our system incorporates a multidimensional indexing scheme, which serves the need for supporting both point and range queries over a set of meta-data attributes. The distributed index is built on top of XOROS, a DHT that supports mutable objects. What is more, we are using Space Filling Curves ( SFCs) to deal with arbitrary multi-attribute queries. | |||||||
| File transfers are conducted using GridTorrent, a grid-enabled, Peer-to-Peer mechanism that allows the aggregate data transfer throughput to scale, effectively coping with flash crowds. | ||||||||
