I just meant, I think we have (the WG has) a responsibility, if we endorse any kind of quad-describing *interchange* notation - or the very idea of interchanging quads at all, in fact - then we have to bite the bullet and specify a semantics (or maybe several semantics) for quads. Alternatively, of course, if quads arent even in our RDF attention focus, we don't need to do that: but then we shouldnt be talking about them at all. > > We have things like the DBpedia dumps already online: > > http://dbpedia.org/Downloads37 > > > To have TriG, the basic syntax, not being able to express basic dumps in the way N-Quads can is possible but its going to place an education cost on explaining that N-Quads -> TriG can't be done without additional > > I would like to see vocabulary on top of the basic syntax, not requiring it's use. Like the time example we had in the telecon, sometimes, there will be data without the full modelling details. Yes, I would like this also. So that various kinds of meaning can be switched on or off, or selected, by (relatively simple and easy-to-add) "switches" like a special triple or some such. But this is going to take some work in the basic RDF machinery to make it possible. Sorry, in haste, more later.
