JSON Schema - the next standard for defining schemas.

Please don't let JSON go the way of XML, with namespaces and complexity.

I wrote this a long time ago: <a href="http://github.com/igorgue/py2json" rel="nofollow">http://github.com/igorgue/py2json</a><p>A Python classes to JSON-Schema SMD translator.

Even disregarding schema validation, I like that it defines standard JSON representations for vCards, events, addresses, etc.

Just another textual factoring of a data composition structure?
