APPA is a P2P data management system that provides scalability, availability and performance for applications which deal with semantically rich data (XML, relational, etc.). APPA provides advanced services such as queries, replication and load balancing. It is being implemented on top on various P2P networks such as JXTA, OpenChord and Pastry and tested on GRID5000 and PlanetLab. The current services of APPA are (see below): KTS, SbQA, P2P-LTR and PeerUnit. The APPA services are used in several projects: Strep Grid4All, ANR RNTL Xwiki Concerto and ANR VERSO DataRing.
