I don't see how CL notation would be any more suited to high- 
performance processing than RDF or OWL.  If I were building CL, RDF or  
OWL implementations, I'd work with whatever internal representation  
(i.e. data structures) and algorithms got the job done consistent with  
the specs.    (05)

Presumably you're talking about the positive fragment of SQL, since  
SQL's "NOT IN" is non-monotonic negation.  If NM constructs are  
included, then the compliance story wrt CL is not so easy to tell.    (07)
