Re: [office] OASIS namespace design and resources

[Svante Schubert <Svante.Schubert@Sun.COM>]

Hi Mary,

of course there is no problem in reusing the official short name of the 
committee. I thought it has been changed from 'office' to 'opendocument' 
and only resists in its previous form in the URL of the TC website. 
Michael might provide further information on this, when he is back from 
vacation.

Would it not be useful in terms of modularity to allow a TC in the 
guidelines to create more than one namespace?
I wonder if there is a way to create more than one namespace by the 
guidelines, when using only a TC name and a versioned NS string.
For this modularity reason I suggested the path behind the versioned NS 
string for our ODF format (in our case the strings of the sub-committee 
name & layer).

Regarding the specific iteration string, it makes perfectly sense in an 
URL to resolve a versioned resource, providing different versions of a 
spec at the same time on the web.
On the other hand, versioning is not supported by the XML namespace 
standard. Changing the namespace URI even in one single character makes 
the XML elements using the changed namespace to complete different 
elements, totally unrecognizable to existing tools, which depend on XML 
techniques as XPATH and XSL.
Furthermore, even if a TC would expand its format XML vocabulary, it 
would reuse the existing namespace (with the old version substring) on 
new elements to avoid confusion on their users.
A versioning with "odf1.2" seems therefore sufficient.

Thank you very much for the namespace template.
Perhaps the link to the RDDL template could be added to the naming 
guidelines, along with links to existing implementations.

Finally did I understand correctly that the GRDDL XSLT stylesheet may be 
hosted at
    http://docs.oasis-open.org/opendocument/1.2/xslt/odf2rdf.xsl
And that it is possible for OASIS to resolve resources dependent on the 
user agent (according to [2]) for URL namespaces?

Thank you very much for your help, Mary.
Seems I got quite a bundle of x-mas wishes here..

Regards,
Svante
