TriAL for RDF: Adapting Graph Query Languages for RDF Data
Summary: TriAL: a triple-oriented algebra (plus recursive Datalog fragment) that queries RDF directly and preserves closure by replacing product with specialized join operators. Shows low-degree polynomial combined complexity, clarifies recursion issues for triples, and subsumes many graph-query languages. (summarized by gpt-5-mini on Feb 09 2026)
