I find the statements in point #3 referring to ODRL and copyright to be
a bit confusing, since actual ODRL licenses are covered shortly after
that. An example of using ODRL to give copyright info would be very
helpful here. (Also note typo at end of point 3 "statementss".)

I don't think this is the best wording to open this section: "DCAT
should rely on persistent HTTP URIs,..." I suspect what is mean is that
when identifiers are used in DCAT they should be HTTP URIs. But that
also is unclear because the DCAT RDF vocabulary by its nature must use
HTTP URIs for all "things". So something else is needed to explain what
the optional situations are where a choice can be made. I'm afraid it
wasn't clear to me what situations the section was referring to.

I found the other revised sections to be clear.
