-
Create your schema

Let the object validate itself
>>> sweden.name = 5 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "warlock/core.py", line 53, in __setattr__ raise InvalidOperation(msg) warlock.core.InvalidOperation: Unable to set 'name' to '5' >>> sweden.overlord = 'Bears' Traceback (most recent call last): File "<stdin>", line 1, in <module> File "warlock/core.py", line 53, in __setattr__ raise InvalidOperation(msg) warlock.core.InvalidOperation: Unable to set 'overlord' to 'Bears'

Generate a JSON Patch document to track changes
