It's pretty pointless to pass a raw JSONValue around because it
doesn't have any semantic information. How do you distinguish between
a JSONValue for a "section" and a JSONValue for a "field"?
What you should do is to traverse the JSON data and build an AST or
model objects (--> MVC) and then use two visitors to ...
1. create and attach your view object and later to
2. fetch and write the JSON data that is to be sent back to the
server.
But whatever you do, don't seek perfection. If your code works and
it's clean you may already be as close as you can get.
