Looks like that I had written in the above quoted > paper anyway. I believe there are two ways to look at this. In the context of XTM the subject indicator is the thing that points at the thing that indicates the subject of a topic. That pointer takes the form of the content of the <subjectIndicator> element. The thing being pointed at an be any resource. I think the conundrum you're pointing out is that we should have something called a subject indicator reference, just as we have "URI reference." We actually *do* have this, in the sense that the content of the aforementioned element shows up as such (notice the mirror of the phrase "*** reference"): <subjectIndicator> <topicRef xlink:href="<URI>"/> <subjectIndicator> This is a reference inside of a wrapper, semantically similar to "URI" inside "URI reference." > -- But I'm afraid what we have put in the RecommendationsGlossary is more like 1.b) and > 2.b) > > -- And ISO 13250 seems to say 2.b) also for subject indicator (or is it clear about it?) > > -- My view is that sticking to 2.a) "subject indicator" = "subject identifier" = "the URI" > is the more sustainable and explainable. > 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).

I think "subject indicator" is the thing in the XTM document that contains the reference (as above), the thing being pointed to is a resource indicating the subject. I don't know that "Subject Definition Resource" is really necessary. Murray ...........................................................................
