Yes, that's the way I plan to *implement* in Redland i.e. add these quads: (subject, predicate, object, <Statement Identifier>} (<Statement Identfier>, isInModel, <Model Identifier>) and similarly for other things like better container support. However, this doesn't say whether <Statement Identifier> is a visible external URI and whether the first quad stands for the statement, reified statement, both, or either. And even if you could decide those, does the statement have a truth value, making it a fact? I wonder if a more formal published proposal (web page), refutation and discussion of proposals might help us move things along here. Dave
