Arms,

Thank you very much for your mail.  I agree that "group the equivalent terms for the same place together" 
is a good approach.

In my understanding, EPUB3 will adopt this approach.  It might be a
good idea to borrow their result as part of OOXML for easier 
conversion from OOXML to EPUB3.

>  However, I do know plenty of DC experts (and critics) who could clarify this and possibly contribute, if informally, to a later activity. 

Thank you very much.  Could you encourage them to review EPUB3 metadata?

Cheers,
Makoto
