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... --- BEGIN # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # Strong Evidence for the Name vs. Location Distinction # # Author: Patrick Stickler <patrick.stickler@nokia.com> # # Copyright (C) Nokia 2002 # # 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. # # Last Modified: $Date: 2002/03/08 09:45:48 $ # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix daml: <http://www.daml.org/2001/03/daml+oil#> . @prefix xsd: <http://www.w3.org/2001/XMLSchema#> . @prefix dc: <http://purl.org/dc/elements/1.1/> . @prefix rdfl: <voc://nokia.com/RDFL-1.0/> . @prefix x: <voc://-/0da5edc7-3265-11d6-8917-0003931df47c> . <voc://identities-r-us.com/253_Patrick_M_Stickler> a x:Person ; daml:equivalentTo <voc://nokia.com/People/Patrick.Stickler> ; dc:title "Patrick Stickler" ; dc:created <val:(http://www.w3.org/2001/XMLSchema%23date)1966-03-31> ; dc:creator <voc://identities-r-us.com/2781891_Irene_T_Stickler> ; dc:contributor <voc://identities-r-us.com/78392_Christopher_A_Stickler> ; x:mother <voc://identities-r-us.com/2781891_Irene_T_Stickler> ; x:father <voc://identities-r-us.com/78392_Christopher_A_Stickler> ; x:worksFor <voc://nokia.com> ; x:hasEmailAddress <mailto:kc4yyy@arrl.net> ; x:hasCV <hrn://nokia.com/CV/Stickler_Patrick_M> . <mailto:kc4yyy@arrl.net> a x:EmailAddress ; dc:title "Stickler, Patrick M." ; dc:created <val:(http://www.w3.org/2001/XMLSchema%23date)1996-09-14> ; dc:creator "Billy Joe Webmaster" ; x:redirectsTo <mailto:patrick.stickler@nokia.com> . <mailto:patrick.stickler@nokia.com> a x:EmailAddress ; dc:title "Patrick M.
