Eric, I found an even better URI for you for the Declaration of 
Independence:

http://id.loc.gov/authorities/names/n79029194.html

Now that could be seen as being representative of the name chosen by the 
LC Name Authority, but the related VIAF record, as per the VIAF 
definition of itself, represents the real world thing itself. That URI is:

http://viaf.org/viaf/179420344/

I noticed that this VIAF URI isn't linked from the Wikipedia page, so I 
will add that.

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?
