OverCite: A Cooperative Digital Research Library

Atlas: Storing, updating and querying RDF(S) data on top of DHTs

“…We have done experiments in PlanetLab 10 as well as in the more controlled environment of a local cluster 11 . The cluster consists of 30 machines where we run 4 Atlas nodes in each machine, i.e., 120 Atlas nodes in the network.…”

“…We omit discussion of the relevant interoperability issues since they can be solved at the level of providers with well-known integration techniques. We also leave open the question of how to interoperate with other relevant P2P networks e.g., the DHT-based digital library OverCite [11].…”

“…Example of such systems are presented in [7,8,9,10,11,12] 1 . More generally, since centralized RDF stores are $ This work was partially funded by FP6/IST project OntoGrid, project "Peer-to-Peer Techniques for Semantic Web Services" funded from the Greek General Secretariat for Research and Technology and FP7/ICT project SemsorGrid4Env.…”

LibraRing: An Architecture for Distributed Digital Libraries Based on DHTs

“…PIRS [24] uses an unstructured P2P network and careful propagation of metadata information to be able to answer queries in highly dynamic environments. Finally, OverCite [17] is a recent proposal to build a distributed version of CiterSeer using DHTs.…”
