Actually, I mean author's opinion about meaning.
Or in Topic Maps slang:
meaning in the scope of author's opinion.

Sorry, I meant RDF Schema as I was talking about RDF.
Are you trying top escape here? :-))

Now again, what is "abbr"? "key"? "full"?
This is why I am asking about RDF Schema.
Lets say I have another document with the following fragment:
<myvocab:desc>Wireless Markup Language</vocab:desc>
Can machine even guess to suggest that these fragments might be
talking about the same thing?
As you are saying yourself , only the graph matters.
Of course XTM do not provide for any magic.
But its processing model makes the job of identifying things much more
Now note that XTM is Topic Maps concept expressed in XML syntax using simple
XLink (XML Topic Maps).
There can be an RDF syntax for Topic Maps!
(As Eric suggested)
If you will keep trying to match XTM processing model with RDF syntax you
up with RTM (RDF Topic Maps)
Hey! then you can get right away the 4TM in the 4Suite! :-))
The problem is that just RDF Topic Maps syntax is not enough.
You will need additional software modules to take care of certain
constraints and the processing model.
Also I believe that RDF graph is completely different from XTM graph.
(even though they are confusingly using similar terms)
It will be very interesting to see if RDF Topic Maps is doable!
I may even try to do something over the coming holidays.
