Three further remarks:
1) I have created and uploaded a W3C GRDDL file (the XSL stylesheet to
create RDF/XML from RDFa and ODF elements from the meta.xml) [1]
2) The namespaces in the proposal have been adapted to the OASIS
policies pointed out by Mary [2]
3) During work on the GRDDL stylesheet it came clear that the RDFa
properties xhtml:content and xhtml:datatype are exclusive.
This and the namespaces have been fixed in an updated draft [3].

Svante

Dear TC members,
I would like to ask the TC to vote on this proposal on the next TC
call. If you have any further questions regarding the proposal, please
send them to me prior to the call.

Dear TC
members,
from my feedback of the W3C Semantic Web Interest group I would like to
combine the previous three existing proposal parts to a single metadata
proposal, consisting of three parts:
Adaption
of W3C RDFa standard
Previously RDFa was not a W3C Recommendation and could not be reused in
our spec, now we are able to adapt the official standard.
Usage
of W3C GRDDL standard
Meant for non ODF applications to extract the RDF graph from our
content.xml, styles.xml and meta.xml streams via a referenced XSL
stylesheet.
Similar adapted by XHTML files using RDFa standard. The location of the
XSL stylesheet is resolved via the URL of the root namespace (ie. XHTML
use case) or via a GRDDL attribute in the root element (i.e. ODF use
case as namespace is an URN and no URL).
Therefore the only effort for ODF applications is a new root element
attribute, the effect enormous.
(After proposal acceptance I would create the XSL stylesheets and place
it on an OASIS server).
Adaption
of RDF mapping to relative URLs
Currently in the new RDF mapping file (manifest.rdf) an arbitrary URN
is
being invented for every ODF element described in the RDF graph. But
this creates troublesome URL alias. Instead the standard will require
that a resource (ODF element) will be mapped directly to its relative
URL.
Currently I am finalizing the overall proposal. In case I will be ready
this evening, I would set it on the agenda of the next TC call.
PS: The previous announced ODF 1.2 proposal of fragment identifier for
URLs
to ODF mime types is being withdrawn by myself, due to the amount of
proposals that have been requested to be considered for ODF 1.2.
Regards,
Svante
