Datalog Expressiveness of Chain Queries: Grammar Tools and Characterizations
Summary: Introduces indexed positive programmed grammars (IPPGs) in three variants to precisely capture chain-query languages definable by linear, semi-linear, and full Datalog under a natural “addressable” condition. Links these formal-language characterizations to prior FO and fixpoint descriptions. (summarized by gpt-5-mini on Feb 09 2026)
