This is great, thanks Imogen!

One thing I noticed with the Demo page is that the JSON seems to have a lot of duplicate objects (e.g. every child object also contains the full JSON for the parent object containing it.) Is there a way we can reduce that duplication to save on bandwidth and RAM?

Maybe one way is to only include an id pointing to the parent object instead of the entire parent object?

[odbol]

I realize now that the JSON is only representing the in memory objects, which I assume have references to the parent objects instead of duplicate objects. That seems fine to me if that's the case; please ignore my earlier comment.
