This is the distinction between a statement and stating and is the point of statement "reification". The point is that since everything is a resource, one can make statements about statements which is how I assume one might make a statement regarding the origin of a statement. suppose: <RDF> <Statement ID="S1"> <subject resource="#peppers"/> <predicate resource="#are" /> <object resource="#hot" /> </Statement> <Statement ID="S2"> <subject resource="#jon"> <predicate resource="#believes"/> <object resource="#S1"> </Statement> <Statement ID="S3> <subject resource="#fred" /> <predicate resource="#asserts"/> <object resource="#xpointer(//Statement[2])"> </Statement> </RDF> Which yeilds the following English statements: "Peppers are hot." "Jon believes that peppers are hot." "Fred asserts that Jon believes that peppers are hot." Jonathan Borden The Open Healthcare Group http://www.openhealth.org
