Not really.  You have to think of the RDF syntax as just syntax.

The first three lines do introduce (define) three variables.
The rule section creates a rule.  The antecedent of this rule is (roughly)
``whenever _s is a &ulan;Artist''.

Undetermined, for now.  (They may be the same as the OWL namespace, or not;
this has not yet been determined.)
