Query Containment and Rewriting Using Views for Regular Path Queries Under Constraints
Summary: Reduces containment of regular path queries under general path constraints to the semi-Thue word-rewrite problem, deriving strong undecidability and identifying a large practical decidable fragment. Gives a constructive characterization for computing optimal constrained view-based rewritings of RPQs. (summarized by gpt-5-mini on Feb 09 2026)
