Indeed: Alistair and I reviewed your guys previous post on this in
detail -- we just hadn't got round to writing back until now ;)

This looks (looked!) good, though I think in terms of the domain model
we may want to think how these particular attributes attach to
particular entities (e.g. Account versus Transaction). However, from
your perspective what matters is the API you're presented with, and if
this is what is wanted this is what the store should provide :)

This is what Alistair and I were reviewing last week along with the
existing "Store" page. The store page is where we're store/domain
model stuff:

<http://wiki.okfn.org/p/Where_Does_My_Money_Go/Store>

I've uploaded the domain model diagram we produced last night there.

(Before you ask, I did link to this before [1] and it is linked from
the main wiki page but perhaps not prominently enough ...)

Rufus
