  2. Overview • Existing Systems • Atlas • LibraRing • Current experiments • Future experiments

  3. The Atlas System • Atlas is a P2P system for the distributed storage and querying of RDF(S) data build on top of the Bamboo DHT (http://bamboo-dht.org). • Atlas is built in the context of the OntoGrid project. • Query-processing algorithms for the evaluation of queries on top of DHTs for RDF data. • Need to test performance by deploying Atlas in hundreds of nodes.

  4. The LibraRing System • Support full-fledged Information Retrieval and Filtering functionality in a P2P environment • A Chord variation is used as the routing infrastructure • Extra routing tables to reduce network traffic: • based on local interactions only • self-maintanable, self-tuning, correction-on-use • Need to test distributed resource and query indexing mechanisms in large-scale experiments

  5. Current experiments • Small-scale simulations only  • Using a Chord simulator • Metrics • network traffic created • load distribution • storage distribution • Need to test on a realistic setting

  6. Future experiments • Deploy Atlas and/or LibraRing on a cluster • Test different resource and query indexing algorithms • Test designed query-processing algorithms in a real implementation • By deploying a Chord-like system on a cluster
