Not that I'm aware of, but if I understand you then this is one of the tasks GoKB is undertaking in partnership with KB+ (the work I mentioned using Refine)

The KBART format was aimed at Link Resolver population - so I'd hope there was some immediate payback on this front, but I don't have any information on this

KBART definitely has ambitions to encompass eBooks as well. There are already some hooks for this (e.g. 'first author' field), and the working group is looking at how ebooks will work I think
