Now you can talk > about that property/value, define a truth-value property for it, etc. I don't think it is a property in the sense of rdfs:Property. But a statement is certainly a part of a document, and a triple is certainly a part of a graph. I don't see any reason we couldn't assign truth values to statements that talk about these things... formally: language: Semenglish {<foo.rdf> docContains "A r B."} entails {<foo.rdf#ThisGraph> graphContains {A r B}}.
