I don't quite follow. Can you be more specific?

I just noticed that e_book_get_book_view() already has a "GList
*requested_fields" parameter. Is that used and/or implemented anywhere? 

The special case relevant for a QtContacts bridge would be to get just
the UID. I don't think that this is covered by the current file backend,
but at least the libebook/D-Bus/backend API should be in place to
implement it.

I have asked my colleagues working on the contacts app in MeeGo about
use cases they care for.
