Description: ==========
        jsonschema
        ==========
        
        ``jsonschema`` is an implementation of JSON Schema (currently in `Draft 3
        <http://tools.ietf.org/html/draft-zyp-json-schema-03>`_) for Python (supporting
        2.6+ including Python 3).
        
        ::
        
            >>> from jsonschema import validate
        
            >>> # A sample schema, like what we'd get from json.load()
            >>> schema = {
            ...     "type" : "object",
            ...     "properties" : {
            ...         "price" : {"type" : "number"},
            ...         "name" : {"type" : "string"},
            ...     },
            ... }
        
            >>> # If no exception is raised by validate(), the instance is valid.
            >>> validate({"name" : "Eggs", "price" : 34.99}, schema)
        
            >>> validate(
            ...     {"name" : "Eggs", "price" : "Invalid"}, schema
            ... )                                   # doctest: +IGNORE_EXCEPTION_DETAIL
            Traceback (most recent call last):
                ...
            ValidationError: 'Invalid' is not of type 'number'
        
        
        Features
        --------
        
        * Support for Draft 3 of the Schema with the exception of
        
            * ``$ref``, and ``extends`` that use ``$ref``\s
        
        * Lazy validation that can iteratively report *all* validation errors.
        
            >>> from jsonschema import Validator
            >>> schema = {
            ...     "type" : "array",
            ...     "items" : {"enum" : [1, 2, 3]},
            ...     "maxItems" : 2,
            ... }
            >>> v = Validator()
            >>> for error in sorted(v.iter_errors([2, 3, 4], schema), key=str):
            ...     print(error)
            4 is not one of [1, 2, 3]
            [2, 3, 4] is too long
        
        * Small and extensible
        
        * Programmatic querying of which properties or items failed validation.
        
            >>> from jsonschema import ErrorTree, Validator
            >>> schema = {
            ...     "type" : "array",
            ...     "items" : {"type" : "number", "enum" : [1, 2, 3]},
            ...     "minItems" : 3,
            ... }
            >>> instance = ["spam", 2]
            >>> v = Validator()
            >>> tree = ErrorTree(v.iter_errors(instance, schema))
        
            >>> sorted(tree.errors)
            ['minItems']
        
            >>> 0 in tree
            True
        
            >>> 1 in tree
            False
        
            >>> sorted(tree[0].errors)
            ['enum', 'type']
        
            >>> print(tree[0].errors["type"].message)
            'spam' is not of type 'number'
        
        
        Schema Versioning
        -----------------
        
        JSON Schema is, at the time of this writing, seemingly at Draft 3, with
        preparations for Draft 4 underway. The ``Validator`` class and ``validate``
        function take a ``version`` argument that you can use to specify what version
        of the Schema you are validating under.
        
        As of right now, Draft 3 (``jsonschema.DRAFT_3``) is the only supported
        version, and the default when validating. Whether it will remain the default
        version in the future when it is superceeded is undecided, so if you want to be
        safe, *explicitly* declare which version to use when validating.
        
        
        Release Notes
        -------------
        
        * Preliminary support for programmatic access to error details (Issue #5).
          There are certainly some corner cases that don't do the right thing yet, but
          this works mostly.
        
            In order to make this happen (and also to clean things up a bit), a number
            of deprecations are necessary:
                * ``stop_on_error`` is deprecated in ``Validator.__init__``. Use 
                  ``Validator.iter_errors()`` instead.
                * ``number_types`` and ``string_types`` are deprecated there as well.
                  Use ``types={"number" : ..., "string" : ...}`` instead.
                * ``meta_validate`` is also deprecated, and instead is now accepted as
                  an argument to ``validate``, ``iter_errors`` and ``is_valid``.
        
        * A bugfix or two
