In this paper, we present the construction of location-based schema caching for query routing at the client-peer in super-peer networks. This cached information is used for directly routing subsequent repeated queries towards their actual resource locations without going via the super peer. Instead of storing the previous query with its result, our proposed approach caches the query with the routing information, which contains the locations where the query data were previously found. This helps avoid outdated results. The paper describes the main processes, including how the input query is decomposed, rewritten, and cached at the client peer.
