Absolutely. in the nested graph proposal we provide a reference to any graph, either user-defined or blank. > The more important point is that this WG, uniquely, is not constrained to use named graphs. > > It can introduce the right conceptual items with the right behaviour > to support the use cases and not be bound by the spectrum of current named graph usage, SPARQL semantics (GRAPH ?g), or Turtle/Trig syntax. But if it can achieve that with named graphs, then that woud be good for everybody. You were always arguing for simple primitives that enable a lot of uses.

But you didn’t provide what I explicitly asked for: arguments and examples for why we shouldn’t use named graphs for annotation purposes. I designed nested graphs to work around the issues discussed in the RDF 1.1 WG note - and successfully so, I believe. What else is there? What could break if we define the usage of named graphs for annotation purposes in a semantically sound way, without touching any other usage of named graphs? I really can’t see the problem and I can’t meaningfully address a concern that is so hypothetical and unconcrete. I also can’t see a reason to let this concern guide the design of annotations in RDF if it stays so vague. Thomas
