This library implements several JSON specs, like `JSON Schema`_, `JSON Reference`_ and `JSON Pointer`_:

* It works on python 2.7, python 3.3 and above
* It is release under the `BSD license`_


Installation
------------

This library has no special dependencies. You can simply use pip::

$ pip install jsonspec


Usage
-----

Let say you want to fetch / validate JSON like objects.

You can extract member of an object with `JSON Pointer`_::

from jsonspec.pointer import extract

obj = {
'foo': ['bar', 'baz', 'quux']
}
assert 'baz' == extract(obj, '/foo/1')


You can resolve member of any object with `JSON Reference`_::

from jsonspec.reference import resolve

obj = {
'foo': ['bar', 'baz', {
'$ref': '#/sub'
}],
'sub': 'quux'
}

assert 'quux' == resolve(obj, '#/foo/2')


You can describe you data with `JSON Schema`_::

from jsonspec.validators import load

# data will validate against this schema
validator = load({
'title': 'Example Schema',
'type': 'object',
'properties': {
'age': {
'description': 'Age in years',
'minimum': 0,
'type': 'integer'
},
'firstName': {
'type': 'string'
},
'lastName': {
'type': 'string'
}
},
'required': [
'firstName',
'lastName'
]
})

# validate this data
validator.validate({
'firstName': 'John',
'lastName': 'Noone',
'age': 33,
})

Other examples can be found in the documentation_ or in the tests_.
