Containment of Shape Expression Schemas for RDF

Summary: Identify a ShEx subclass with 'shape graphs' and a natural RDF→shape-graph embedding; embedding suffices for containment and is iff for deterministic shape graphs, yielding tractable containment. General shape-graph containment is EXP-complete; arbitrary ShEx decidable. (summarized by gpt-5-mini on Feb 09 2026)
