Rewriting XPath Queries Using Materialized Views

Summary: Studies XPath rewriting over materialized views for server-side optimization and client-side semantic caching. For a practical fragment, existence is coNP-hard and minimal rewriting lies in Σ₃^p; three restricted subclasses admit polynomial solutions and a sound, complete algorithm.
