There may be a conflict. The assertion is self contained and
sensible, but how do you merge that graph with this one:

http://www.markbaker.ca/index.html urn:prop34 "472920"

Is this about the page or the person?

Somehow this has to be sorted out if RDF is going to claim any
value in merging datasets without the inference engines doing weird
stuff. Sense doesn't allows follow from consistency. One way to do
this is to embed the meanings of properties in your RDF code,
either directly or via an inference mechanism that sucks in RDF
schemas and follows what's laid down in the model theory. I think
it would have been nice to be able to do straight matching on the
URIs.
