[from an HTML mail, imagine there's little > in there] -----Original Message----- From: www-rdf-interest-request@w3.org [mailto:www-rdf-interest-request@w3.org]On Behalf Of MDaconta@aol.com Sent: 14 November 2002 17:13 To: fmanola@mitre.org; www-rdf-interest@w3.org Subject: Re: The semantics of blank nodes [snip] How is an RDF application processing this to know that the URI on line 5 is an accessible web page but the URI on line 9 is just an identity? Especially when both specify http: as the protocol. I know this is off topic but some pointers on this would be helpful. One way I can think of is to add the <dc:type> property to the web page and then you can assume anything without a dc:type is just an identity (not a foolproof technique unless the dublin core folks add a dc:type value for "identifier" or "name"). [end quote] At the level of RDF both URIs are "just an identity". I agree that it would be useful for many applications to know if you could retrieve a representation (note that a resource is not the same as the bytes that get sent down the wire - see http://www.w3.org/TR/webarch/#resource-interactions), however there may not be a good general way of doing this, and certainly it should happen at a level above RDF.
