REST API repeats values in JSON fields

[mo-seph]

The values in a JSON field are repeated several times in the JSON output of the rest API when querying.

Example object (shortened syntax for clarity):
{ @id: obj1, children: [ @obj2, @obj3, "extra", "extra" ] ... }

Python client returns (as expected):

u'obj1': { u'@id': u'obj1',
                        u'children': [ { u'@id': u'obj2'},
                                       { u'@id': u'obj3'},
                                       { u'@language': u'',
                                         u'@type': u'',
                                         u'@value': u'extra'},
                                       { u'@language': u'',
                                         u'@type': u'',
                                         u'@value': u'extra'}],

REST API returns:

It seems to be a difference between what happens with using ?id=obj1 versus /query … q={@id:obj1}.
When the client does searches, it adds depth=3 to query. This fixes the problem, but doesn't seem to relate to what I'd expect depth to do- for N=[-Inf..0], I get the duplicated output. For N=[1..1000], the output is correct. (For N="chicken" the server falls over.)

I would have expected N > 1 to fill in referenced objects, i.e. the children field would be replaced by the content of that object?
