Subject: Re: [office] metadata and XMP (was: [office] metadata (OpenDocument TCMeeting Minutes ...))
Hi, there are a number of points in your post, and I'd like to address them in different threads, so I start of with the XMP related ones and cover the other topics in different posts... Bruce D'Arcus wrote: >> [Minutes...] >> This mapping should also conform to the subset of the RDF data model >> that XMP is using >> The mapping should map some of the meta:-namespace properties to dcq >> properties if there are appropriate ones available. > > These two are not consistent, as XMP notably does not use DCQ.

This XMP/dcq redundancy (and others) is indeed something we need to find a way of dealing with. I am also not saying, that XMP should be the framework. However, I belive, that the default metadata model can be mapped to an RDF model that is consistent with the subset of RDF that can be modeled by XMP. That way, an XMP enabled application could use the metadata in an OpenDocument file (the mapping would need to be implemented in the XMP framework for this to work). > [...] > The reason why I say phase 2 will be difficult is that I don't think XMP > is acceptable as is.

I share these concerns, mostly because I am also a strong beliver in the usefulness of attaching statements of metadata to individual parts of a document. The syntactic way in which that can be done does not matter that much to me. One of the things that I like about XMP is, that it is out there and actually being used. So as I stated above: while I don't think that XMP as it is today should be the normative framework for OpenDocument metadata, I would very much like to see the XMP framework to be able to use as much of the metadata in an OpenDocument file as possible. E.g. if a document management system has build in support for XMP, you can use the XMP data in your PDF documents stored in that system. If the XMP framework was able to use the metadata (at least the part that is attached to the whole document) in an OpenDocument file, you could use OpenDocument as a storage format in the system just like you would do with PDF. A user could then use OpenDocument for files that are in the edit-cycle and use PDF for published documents. Plus, the metadata of an OpenDocument file wo0uld also be usable in its PDF version. -- Lars Oppermann <lars.oppermann@sun.com> Sun Microsystems Software Engineer - StarOffice Sachsenfeld 4 Phone: +49 40 23646 959 D-20097 Hamburg Fax: +49 40 23646 550 http://www.sun.com/staroffice
