Thanks Michael for taking the initiative with this (and I answer some
of your questions further down).

I agree that straight profiles are the way to go if at all possible.
One potential issue with this is that you can only store one form of
MRS (as far as I know), and may want more than one in the corpus.

parse trees, derivation trees (possibly in the same structure) MRS
(possibly as dependencies).

I would be happy to submit part or all of the Hinoki treebank (with
the proviso it is a little out of date).
