oops, right. My point was only that we don't need to overload each and every
use of a date on the "dc:date" property.

right, so neither can RDF say that "dc:date" is a date either... this is an
orthogonal issue to the original discussion, but you are correct.

In any case I hope you will agree that given

site:last-modification-date rdfs:domain ex:Site .

foo:bar site:last-modification-date "2003-03-05" .

that we can infer:

foo:bar rdf:type ex:Site .
