RE: Explicit Disambiguation Via RDF bNodes, more Process

blah below, to cut it short :

I'm saying that if

the URI http://www.markbaker.ca/index.html is equivalent to the set

[markBakerThePerson(person), theWebSiteAtThisURL(website),
theLiteral"http://www.markbaker.ca/index.html"(string)...lots]

where markBakerThePerson, theWebSiteAtThisURL etc are just local identifiers
I'm using - anonymous nodes even - for elements in the URI, which is a set
btw, - and (person), (website) etc are types/classes defined in shared
schema

and 'livesIn' and 'respondsToGET' are predicates in shared schema that apply
to (URI.person, place) and (URI.website, string)

and someones states that http://www.markbaker.ca/index.html  livesIn Miami

and someone states that http://www.markbaker.ca/index.html respondsToGET
Error404

then I can reasonably ask

Where does  http://www.markbaker.ca/index.html  live?

and expect the answer 'Miami'.

Gawd help us if they are, but if people here are able to bend & twist the
meaning of URIs, doesn't that suggest at least that it is possible? (and
thus probable 'in the wild')

If systems are designed so that 'one' represents 1.00, then they may not
work if someone uses 'one' to mean 1.01.
Whereas if systems are designed to accept 'one' as 1 +/- 0.1 then there's no
problem. This in a way is orthogonal - better would be to say that 'one' can
mean 1.00 or a string of characters or myself.

Eye for 1.00 am trying to look at ways of reducing ambiguity.

Hmm - I believe it might have been said before on this list - 'a web page'
is only one possible interpretation, even accepting that the http: means the
HTTP protocol.

What I meant here is that the application on machine X may use the
identifier ABCD to refer to the web page http://... and all the assertions
it finds about it. It may use another identifier to refer to the person
who's home page shares the same URI.

  Do you have an example of
>how to solve the simple problem I pointed out?

Sorry, I've gone back through the last dozen or so of your posts and I can't
find the problem - could you please repeat it. Here's a question in the
meantime, you said :

[[[
The anonymous (or named if you want) node:
[http://www.markbaker.ca/index.html dc:Creator]
Identifies the person.

The node:
[http://www.markbaker.ca/index.html]
Identifies the page.
]]]

If I am to use this information in my inference system, how exactly do I
know that the first of these identifies the person, and the second the page?
(and yes, I would like you to spell it out)

Cheers,
Danny.
