I assume by "River class as an individual" you mean as something other
than as an instance of rdfs:Class (which is what the above definition
says).  If that's the case, then how about (assuming appropriate
namespace declarations):

     <rdf:Description rdf:about="#River">
         <dc:creator>Roger Costello</dc:creator>

Or if you're looking for something more complicated, can you describe
the sort of complication you're interested in?
