Re: Properties of Resources that Need More than One URI to be Identified

I understood that before; however, my question was probably poorly posed.
Sorry for any confusion.

Here is my current understanding.  I am under the impression that there are
two different types of nodes in RDF that can be a subject: a URI reference
string or an anonymous node.  Obviously, RDF is only useful for describing
resources that can be represented by one of those two.  My question is: are
there non-anonymous resources that cannot be identified by a URI?  If so,
how then can they used in RDF graphs?  And what are some of their
properties?

Tom Passin seems to suggest that such a resource should be assigned an
arbitrary URI [1].  Both of you think that predicate/object pairs could be
added to further describe the resource.  Am I interpreting your posts
correctly?  In the case of the unreachable file [2], could I specify the
following?

<an-arbitrary-uri-for-my-resource> <rdfs:isDefinedBy> _:b .
_:b <rdf:type> <rdf:Seq> .
  _:b <rdf:_1> <a-computer-scheme-uri> .
  _:b <rdf:_2> <a-file-scheme-url> .

Am I correctly understanding you so far?
