Joshua, you might want to specify that the labeled graph reppresentation 
of RDF is an approxiamtion and works just in certain cases since lables 
themselves must be URIs  which can be subjects or objects of rdf 
annotations. So labels are indeed nodes as well and this makes RDF not 
equivalent to a labeled graph but rather ... huh to somethingmore 
complex :-)?
