RDFa? I really don't know the implementation details, but the proposal in general envisioned two primary cases: 1) simple content tagging ("this text is the title" and so forth) 2) more complex structured fields ODF is not HTML, and so we had some liberties that allowed us to keep the in-document metadata fairly narrow, and off-load more complex stuff to in-package RDF/XML (which can in turn point to document content). So a subset of RDFa would be used for #1, and RDF/XML + a new metadata field would often be used for #2. As an example, then, for the citation case, you'd have metadata fields to hold the rendered content in document, and then you'd attach those fields to RDF/XML descriptions stored in-package. An extension would work with these data. AFAIK, the first implementation of the support in OOo is likely to just put the API in place, which developers would in turn build on. Svante Schubert from Sun posted slides from a talk he did on this: <http://www.slideshare.net/jza/an-rdf-metadata-model-for-opendocument-format-12> You'll note, though, he doesn't go into much detail about the UI. I personally would like to see enhanced metadata enable the sort of UI enhancements that are barely hinted at with some of Jeni Tennison's work with RDFa in XHTML, where the UI can overlay richer information about document content [1].
