Subject: RE: [office] OASIS namespace design and resources

[mpm] While the name of the TC was changed quite some time ago, the TC itself did not reconstitute and therefore the mailing lists, kavi groups, and all associated resources must still bear the 'office' moniker. > > 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).

[mpm] Versioning the namespace is very different from maintaining multiple iterations of the specification - so while the namespace itself doesn't change, the namespace document associated with that namespace is updated each time a new release (CD, PR, CS, or OS) is approved. Having separate directories for each stage is just good housekeeping from a directory standpoint. > > 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? [mpm] No, it must be hosted at http://docs.oasis-open.org/office/... Currently, we always resolve to the namespace document regardless of the user agent. I'm not sure what else might be possible - copying Robin Cover on the thread as he may have more experience/knowledge. > > Thank you very much for your help, Mary. > Seems I got quite a bundle of x-mas wishes here..
