Re: NEW DRAFT: Documentation and OA/OAX

It is not a asbsolute requirement in W3C that a single namespace
corresponds to a single document. For instance, in PROV, we moved from
having separate namespaces to using across the
different documents PROV-O and PROV-DM.

It does bring it's own set of worries, such as if you resolve for RDF/XML, you only get the PROV-O terms, and
not PROV-AQ terms like prov:hasProvenance. In PROV, we intend to present a
'merged' ontology when you resolve the namespace, with the standalone
ontologies reachable from the different documents. The HTML browser gets a
landing page pointing to the different documents; this landing page and owl
can be updated independently of recommendation track (for instance to fix
syntactic errors or keep up with technical OWL spec changes).

Some of these challenges disappear if you end namespace with a / rather
than #, so individual terms can redirect to correct spec/owl.

That said, I agree that the current split is not very ideal ; but I am not
sure about going for a single document. I agree with Jacco in that a simple
and straight forward 'core' specification makes it much more likely for the
standard to be picked up, understood and used.  It is a bit of the beauty
of the current OA spec, in my view, and I think several things could be
moved out of the current "core".

So I would generally not prefer a big, merged document. Is that what you
are proposing? I would not mind a single namespace though.

The OAX could be made more of an "OA Expanded" rather than "OA Extended";
showing the preferred way to do common scenarios such as CSS styling, sets,
HTTP headers and other more "complex" structures that perhaps do not need
to be in the core. With this I would downgrade the OAX role as a sandbox.
Such new features should be in additional mini specs before being formally
added to OAX.

I would not argue for a CSS2 kind of modular splitting.

Another alternative is however to do a multipage split, so you get
"chapters" that are not as independent as separate specs, but more modular
than the single HTML. Many do however like to download and print, and this
could be tricky unless a "all in one" alternative version is made available.
