Subject: Re: [office] Single ODF 1.2 metadata proposal

Not to beat a dead horse, but wouldn't we be better off with XMP?

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 <http://wiki.oasis-open.org/office/Change_Proposal_for_ODF_1.2_Metadata_-_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 <http://wiki.oasis-open.org/office/Change_Proposal_for_ODF_1.2_Metadata_-_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 <http://wiki.oasis-open.org/office/Change_Proposal_for_ODF_1.2_Metadata_-_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PS: The previous announced ODF 1.2 proposal of fragment identifier for URLs to ODF mime types is being withdrawn by myself, due to the amount of proposals that have been requested to be considered for ODF 1.2.
