Thanks Henrik,
I guess things are much simpler if all parts know enough about the data
format to be able to do what they need to do. I think I was imagining
things more complicated than they need be.
Thanks Ben, this was interesting...

Robotlegs has good press. I wonder what people on this list prefer?

"The data changing should be done in an adapter that the controller puts
in between the model and the view."
So the problems arise because the data that isn't quite what the model
stores, or isn't quite what the views use.
At the same time the controller shouldn't know about requirements of the
model and views, but in this world of isolation and 'not knowing' about
other things we need adapters that do know the details of other parties.
Do all systems need adapters that convert data into the appropriate format?
It is fine for the controller to know the identity of the formats
involved. But understanding them is probably overkill.
A well designed system will often have situations where the view and
model use the same format, meaning that there is no need for any adapter.
