Subject: Re: [tm-pubsubj] Subject Indicator and Subject Indicator Reference(again)



* Bernard Vatant
| 
| 1. What is the "subject indicator reference" ?

I'd say 1.b), that is, the URI. (This is what your proposed definition
in the REC says.)

| 2. What is the "subject indicator" ?

It's the resource (in this case, document) referred to by the URI.
That is, 2.b).
 
| -- But I'm afraid what we have put in the RecommendationsGlossary is
| more like 1.b) and 2.b)

It is.
 
| -- And ISO 13250 seems to say 2.b) also for subject indicator (or is
| it clear about it?)

It doesn't use the term. It talks about subject descriptors and how
the 'identity' attribute refers to them.
 
| -- My view is that sticking to 2.a) "subject indicator" = "subject
| identifier" = "the URI" is the more sustainable and explainable.

That's quite simply wrong. If you have a topic map that uses a subject
indicator it's quite clear that it contains a reference to something
that indicates the subject. It's also quite clear that the reference
is the URI, while the thing that actually does the indication is the
resource. Now, what is the most useful is actually the subject
indicator reference, but that doesn't affect the terminology.

The URI is clearly a kind of subject identifier, but I think we should
steer clear of that term, since we don't need it, and SIR is easier to
understand. 

The xlink:href is what asserts the reference, by the way. It is *not*
the reference. This is the difference between addressing and linking.
The xlink:ref is the link, the URI the address.

Would it help if I sat down and wrote up an explanation of this as I
see it, which you can then either shoot down or adopt? (Would solve
the "what do we put in instead of the glossary" problem at the same
time. :-)

| In that case we have no name for 2.b) in the case the resource is
| not a declared Subject Definition Resource (the quoted example). But
| do we need a name in that (non recommended) case?

We have all the terms we need already. We just need to be clear on
what they mean. :-)
