I haven't thought through this in code, but my gut feeling says we need
to tie the href and the object that it references together more tightly,
i.e. I think we'd need something like
array :machines do
reference :machine, :attribute => :href
end
where :href is the default for :attribute. At that point, we should
probably copy Rails even farther and say
has_many :machines, :attribute => :href, :class => Machine
where :attribute and :class default to :href and Machine
(singularization of the association name)
One of the advantages of tying things together like that is that it
gives us a lot of flexibility if the association itself should gain
attributes in a future draft, e.g. so that the collection of volumes
attached to a machine gets its own URL.
And we probably want a has_one, too.
