I agree with you. Viewing a URI as a name, it's impossible to use the lexical structure of the name to signal the type of the thing referred to -- Person, Graph, Document, etc. There are too many different types. The syntax structure does help, e.g., the triple subject property object conveys some information concerning the types of the referents. ============ Dick McCullough knowledge := man do identify od existent done knowledge haspart list of proposition ----- Original Message ----- From: Paul Prescod To: Richard H.

I'm not clear on your opinion of Doug's proposal. ;) But you did change the subject line so I guess we'll treat this as a new thread. > For example, if we want to talk about Linus Torvalds in the context of > URIs & RDFS, we might have three different somethings that we need > three different names for: > > Linus Torvalds the person > a document that contains RDFS statements that describe facts about > Linus Torvalds > a graph that contains nodes and links that describe facts about > Linus Torvalds > > My impression, based on a few RDF-interest emails, is that much > confusion has been generated by trying to use one URI when three URIs > are required. I think that you misunderstand the debate. It is easy to make up three URIs for Linus Torvalds or ten (let's not forget his home page and email address and ...). The question is whether the syntactic form of the URI restricts whether it refers to him, or his home page or the graph or ... Seth says: > Linus Torvalda the person > http://foo/#LinusTorvalds > a documdent that contains RDFS statements that describe facts about > Linus Torvalds > http://foo/ > a graph that contains nodes and links that describe facts about Linus > Torvalds > http://foo/#ThisGraph But an equally consistent position is: Linus Torvalds the person http://foo/LinusTorvalds a docudent that contains RDFS statements that describe facts about Linus Torvalds http://foo/LinusTorvaldsInRDF a graph that contains nodes and links that describe facts about Linus Torvalds http://foo/LinusTorvaldsGraph Insofar as RDF care NEITHER about the syntax of the URI _nor_ the data referred to by the URI, why should WE care? Why impose a syntactic convention at all? RDF offers me ways of saying that InRDF is the RDF representation and Graph is the graph representation of the LinusTorvalds concept. If Seth wants to use his convention then he can, but he should also use RDF statements to make explicit the relationship. Paul Prescod
