ABSTRACT
GridVine is a Peer Data Management System based on a de-
centralized access structure. Built following the principle of
data independence, it separates a logical layer ­ where data,
schemas and mappings are managed ­ from a physical layer
consisting of a structured Peer-to-Peer network supporting
efficient routing of messages and index load-balancing. Our
system is totally decentralized, yet it fosters semantic inter-
operability through pairwise schema mappings and query
reformulation. In this demonstration, we present a set of
algorithms to automatically organize the network of schema
mappings. We concentrate on three key functionalities: (1)
