I've worked a bit on this item and made attempts to formalize three semantic extensions:

* owl:imports (formally explains how owl:imports works in RDF datasets)
* web datasets (formally defines that stuff published on the web is asserted)
* direct graph semantics (permits "literal" immutable graphs)

http://www.w3.org/2011/rdf-wg/wiki/TF-Graphs/Minimal-dataset-semantics#Possible_Semantic_Extensions

I'm not proposing that we should standardize any of this; the intention is merely to explore how flexible/extensible the semantics proposed on that page is.

Again, I'm not really good at this formal semantics stuff, so this might all be spectacularly wrong.

Best,
Richard
