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.
