json_schema 0.3

json_schema is a JSON-based schema validation package.

JSON-based means that its feature-set is adjusted to JSON, but it doesn’t require JSON data: any Python objects are fine, as long as they’re of the primary Python types.

Let’s start off with an example:

from json_schema import Schema, AnyInteger

my_schema = Schema([u"set-temp", {u"degrees": AnyInteger}])

if my_schema.validate([u"set-temp", {u"degrees": 10}]):
    print "Valid!"

It’s a very declarative way of saying how your schema looks. With the architechture that json_schema is built on, you can customize pretty much anything.
