Re: [cam] RE: OASIS Naming Rules

["David RR Webber" <david@drrw.info>]

Martin,

The answer for the Schemas IMHO is there already:

 http://registry.oasis-open.org

I've created a node for jCAM already - and we can
extend that for approved committee documents.

Since the registry supports http-binding access - you
can go from a URL to the exact item in the registry too.

We can discuss this offline anyway - there's definately
ways to work this - such as putting a HTML page in
Kavi that then points to the documents themselves
on links, etc - and link to that off the TC frontdoor page.

Thanks, DW.

Dear all,
I really did not want to open a can of worms.  I just wanted
some guide lines on how we might name our namespaces and also if we
chose http:// based ones that we might have a home to which the URL
pointed.

The message I am hearing is that it is a can of worms and that
we are probably best to resove it at TC level.  As to the home fo rthe
schema files etc I think I will take it up with Scott and see if there
can be a space outside KAVI for some of this info or a URL rediction
tool that can work for http://oasis-open.org/tc/tcame/....

As to the use of versioning.  Well I really did not expect the
debate I expected a dictated solution from the Oasis board as I feal
this kind of thing is part of the brand as in the W3C, but hey I am sure
people will now say that even they are inconsistent:)

Yes, but...  Many languages declare their intentions ahead of time for
what constitutes a "namespace version upgrade", which gives you the
ability to predict tighter semantics for an n.m to n.m+1 change or an
n.m to an n+1.0 change.  SAML is one; it will stick with n.0 until a
major backwards-compatible revision is done, and anything in that
namespace that *hasn't* been changed will have the same semantics as it
used to.

And if you register a URN namespace foo, you have the right to
officially declare that urn:foo:...:... has subfields that mean
particular things, and thus you can make such intentions formal.
