nowhere is there mentioned a IRI there,
IRIs are not forbidden either, and Andrew's description makes me think
the "concept URI" *is* the "term".
The question is: how does this help any of us? It may look like it is
a "term", but what is a client meant to do with all this information?
So if Tim Bray uses
<category scheme='http://www.tbray.org/ongoing/What/'
term='Places' />
Then what am I meant to do with this info? Since scheme is a URL I
can presumably go there to find something. But what?
Term is not defined to be a URI, and in the above example it is not,
and so why should I do anything with the term below?
<category
scheme="http://my.scheme.net/my-vocabulary/";
term="http://my.concept.net/my-vocabulary/13745";
label="cats"
/>
What I am proposing is that we put forward some best practice to
formalize a useful and RESTful way to publish this information, so
that clients can use it. With APP we could do something like this: we
could define for example that when entries are published and they
contain categories that have a scheme that is accepted by the
collection, then the entry will be found in the feed that is to be
found either by appending scheme+term or in the catid location I
mentioned previously.
So if Tim Bray posts an entry containing
<entry>
...
<category scheme='http://www.tbray.org/ongoing/What/'
term='Places' />
</entry>
and his collection manages the <http://www.tbray.org/ongoing/What/>
scheme, as defined perhaps in the service document, (and perhaps we
can place the list of available categories at that scheme location!)
then his client will know that the entry will also be found in the
<http://www.tbray.org/ongoing/What/Places> collection.
Now this would be useful for an APP publishing client, and it would
be useful for an APP reader, because it could find some useful
information at these various locations, and it would save us having
to define an unending number of link relations that parallel the
categories we have, when it is in fact clear that everybody intends
to use scheme+term as a uri.
