Agreed, on all counts.

However I'd like it to be expanded in scope slightly to also cover information derived from non-RDF pages which are being crawled (pure self-interest, as this is where we get most of our data). It's slightly different from a modelling point of view, as foo.html doesn't typically contain any actual triples, just information which cause triples to be asserted.

That, in combination with “1.3 Graph Changes Over Time”, and “1.5 Exchanging the contents of RDF stores” captures our most challenging data representation challenges.
