Some folks seemed to have some problems with the .n3 file I
sent previously as an attachment, so here is the contents of
that file verbatim...

#  Strong Evidence for the Name vs. Location Distinction
#
#  Author: Patrick Stickler <patrick.stickler@nokia.com>

#
#  The following RDF/N3 statements aim to illustrate the importance
#  of a formal and consistently upheld distinction between the
#  names of locations and the location-independent names of
#  non-location resources.
#
#  The following claims are presumed by and hopefully validated
#  by the statements below:
#
#  1. URIs are names of resources.
#  2. Locations are a special kind of resource.
#  3. URLs are names of locations.
#  4. URNs are location-independent names of non-location resources.
#  5. Non-location resources may be accessible at one or more locations.
#  6. The Web and SW architecture must allow one to make statements
#     about:
#       a. Non-location resources.
#       b. Location resources.
#       c. The location of non-location resources.
#       d. The URIs themselves.
#
#  This means, among other things, that:
#
#  * An http: URL by which one retrieves a representation of a web page
#    does not name/denote the web page, but only the location from which
#    the web page representation was obtained; and for some applications,
#    such as a web browser, such 'nameless' reference (the resource that
#    resides at the following location) is sufficient. For other
#    applications, such as resource and site management, it is not, and
#    it is necessary to differentiate between the name of the location
#    and the name of the resource accessible at some location.
#
#  * A mailto: URL does not name/denote a person, but a point of access
#    bound to a specific set of protocols, though one may be able to deduce
#    the identity of that person by their association with that URL.
#
#  * Statements made about a URL are about the location, not the resource
#    which may reside at that location.
