[det]json_to_prolog(+JSON, -Term)

Translate a JSON term into an application term. This transformation is based on :- json_object/1 declarations. An efficient transformation is non-trivial, but we rely on the assumption that, although the order of fields in JSON terms is irrelevant and can therefore vary a lot, practical applications will normally generate the JSON objects in a consistent order.

If a field in a json_object is declared of type boolean, @true and @false are translated to true or false, the most commonly used Prolog representation for truth-values.
