GridVine: an Infrastructure for Peer Information Management

GridVine is a semantic overlay infrastructure based on a peer-to-peer (P2P) access structure. Built following the principle of data independence, it separates a logical layer — in which data, schemas, and schema mappings are managed — from a physical layer consisting of a structured P2P network supporting decentralized indexing, key load-balancing, and efficient routing. The system is decentralized, yet fosters semantic interoperability through pair-wise schema mappings and query reformulation. GridVine’s heterogeneous but semantically related information sources can be queried transparently using iterative query reformulation. The authors discuss a reference implementation of the system and several mechanisms for resolving queries collaboratively

GridVine is a Peer Data Management System based on a decentralized 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 interoperability 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) the sharing of data, schemas and schema mappings in the network, (2) the dynamic creation and deprecation of mappings to foster global interoperability, and (3) the propagation of queries using the mappings. We illustrate these functionalities using bioinformatic schemas and data in a network running on several hundreds of peers simultaneously
