A complete decidable characterization of polynomial rules P yielding bilinear associative commutative P-products on series is given, together with decidability of equivalence for the associated P-automata.
SPARQL, multiset Datalog, and multiset relational algebra are expressively equivalent for AND, UNION, FILTER, EXCEPT, and SELECT.
