I think dc:creator is supposed to take a string instead of an object or URI.  So I think you should use a different predicate, which takes a class as an object.  Then you can have an object that describes Thomas Jefferson and include both his name and gender, links to authority records, etc.:

How might the robot express this fact in RDF/XML? The following is my first attempt at such an expression, but the resulting graph (attached) doesn't seem to visually express what I really want:

> Am I doing something wrong? How might you encode such the following expression — The Declaration Of Independence was authored by Thomas Jefferson, and Thomas Jefferson was a male. And therefore, the Declaration Of Independence was authored by a male named Thomas Jefferson? Maybe RDF can not express this fact because it requires two predicates in a single expression, and this the expression would not be a triple but rather a “quadrile" — object, predicate #1, subject/object, predicate #2, and subject?
