As Paul Rogers pointed out with his implementation POV (see the Buoy POV example at http://www.riakrest.com) it enables really nice declarations of data structures that are subsets of the data stored in Riak. Is there any notion of building that into Riak at the bucket level?
There is no current plan to reimplement read/write mask capabilities
for the HTTP interface. We found that they added more confusion than
they added useful features. Indeed, POV was interesting, but it was
not realistic for concurrent access by multiple actors.
We've found that one good way to get similar functionality (partial
reads & updates) is to break objects into smaller logical pieces, and
then use link-traversal to grab the pieces you want.

It is not yet, but it is coming. In the very near future, either for
this release or right after, we intend to add "pre- and post-commit
hooks" to allow applications to tie in at that level.
