I think you make JSON's point for it. It has a single, unambiguous, bidirectional mapping to native data structures in all dynamic languages; indeed that is its design goal.
XML does not map well to language structures, except in languages designed explicitly to manipulate it. The duality of elements and attributes means additional choices at each encode/decode boundary, and guaranteed ambiguity. To continue the argument made by mark Nottingham and Tim Bray, having to choose between attributes and elements at each point imposes the same overhead at a different layer than having to choose between xml and json. Yes, this natural mapping does not hold true for C, because C doesn't have a native dictionary/hashtag data structure. C doesn't make XML or anything else easy either, but C programmers are used to that. On Mon, Apr 23, 2012 at 10:56 PM, Paul E.
