(apologies if you receive this twice - the first send does not seem to
have worked).

Following the points below, I'd like to clarify something minor
(though possibly important for our mapping to other vocabs such as
Dublin Core).

The example says "government (gov) publishes RDF data (f1) along with
its provenance (prov) on a portal with a license (li1); the rdf data
is now available as a Web resource (r1)" (and similarly for f2/r2)

But what does it mean for f1 to be "published" as opposed to being
"made available" as r1?  Is f1 something uniquely identifiable,
accessible, and for which anyone can ask the provenance, or not?  What
distinction is being drawn?
