ViP2P is a fully functional Java-based platform for the efficient, scalable management of XML documents in structured peer-to-peer networks based on distributed hash table (DHT) indices. We exploit indices (or materialized views) deployed in the P2P network independently by the peers, to answer an interesting dialect of tree pattern queries. There is a query (and view) language, a rewriting algorithm, view definition indexing strategies based on the DHT and much more…

LiquidXML
LiquidXML is built on top of ViP2P. Its main feature is to automatically select and continuously adapt the set of materialized views on each peer, to improve query processing performance both for the view holding peer, and for the other network peers. LiquidXML continuously adapts by adding more materialized views and/or replacing low-utility views with more useful ones according to the query workload.
More screenshots of the system can be found on this screenshots page. For more infromation concerning LiquidXML, you can contact Asterios Katsifodimos or Jesús Camacho-Rodríguez.
