I agree that there is little time left. Believe me I try to focus with 
my questions on this list on the remaining problems.

We might split the RDF metadata problematic into two general areas, 
which affect ODF

   1. The subject is in the content
   2. The object is a literal and in the content.

Concerning the first, I raised yesterday the question about the 
restriction on absolute RDF references.
Concerning the second, in case the RDF is being mapped to RDF XML it is 
identical with the XForms use case we already have in ODF. We might even 
reuse validation mechanisms.
Certainly presumed that the current XForms implementation would be 
widened to acces Text fields aside of the current Form controls only and 
possibly enhanced in some other ways.
It might even be assumed that a 'RDF user interface' - whatever it might 
look like - take advantage of the XForms implementation and would even 
look similar to an User interface that you have in mind for RDFa. The 
XForms syntax / implementation might look more complicated as RDFa but 
we might reuse an existing ODF syntax / implementation by extending it 
to our basic needs.

XForms becomes reasonable, when preexisting RDF XML file comes into 
play. For example, the user would like to import his RDF XML, for 
instance the VCARD XML as shown in 
http://wiki.oasis-open.org/office/ExampleDocument/UseCaseUsingXForms 
reuse, edit and extend it and export it later from the ODF document.

Bruce, please understand that this is not meant as a provocation, but I 
am not aware, how we would address this scenario by RDFa. I plainly have 
no concrete idea about it.
Would the RDF XML being stored in the RDFa approach as well and the 
literal being duplicated - once in the RDF XML and once in the text?
