tm-pubsubj-comment@lists.oasis-open.org is a public list isn't it?

 

Generally, within the XML community: what might be machine-readable but not human-readable?

Nothing, imo.

Hi Thomas,

I'm replying to you directly because I do not have privileges to post to the working group list.

If you use a GET request like "[psi-service-url]?id=xyz" for the PSI, the database service can return the topic having id=xyz in any agreed format, i.e. XTM. This *is* human-accessable. Why create another version?

I see a clear distinction between the Published Subject Indicator and the topic which reifies the indicated subject. I think from your comment that you do too and that you see the psi-service as being the way to bridge this gap. Is that correct ?

I was replying to the suggestion that the indicator itself should be dereferenced to provide a human-readable resource. In either case (direct dereferencing or dereferencing via a service) I don't think that a publisher should always be expected to provide a human-readable resource for every PSI. Of course, I recognise that there is likely to be a topic for every indicator and in fact, I would argue that the *only* machine readable metadata that should be provided when a PSI is dereferenced should be the URI of the topic which reifies the subject.

Cheers,

Kal
