Re: URIs / URLs

Interesting notion. In actual fact, I would suggest that there is a
little confusion here in that (as you state) all URIs identify some
resource, but some of these are retrievable and some aren't; I would
suggest that the ones that are could be considered to resolve to a
data:, URI, and so in that sense some resource which is also "on the
Web". i.e. a Web-resource would be another URI.

Agreed, although there is a sliding scale of both time-based
persistence, and quality-of-service persistence.

But RDF can make assertions about any resource than can be identified,
not just resolvable ones: all URIs!
