That's exactly the connection between queries and rules: a 
logical formula (with free variables), no matter in which
language it is expressed (OCL, Prolog, RDF, OWL, etc), may 
play both the role of a query body (without result 
presentation/structuring) and the role of a derivation 
rule antecedent.
