-==========
-jsonschema
-==========
-
-``jsonschema`` is an implementation of `JSON Schema <http://json-schema.org>`_
-for Python (supporting 2.6+ including Python 3).
-
-.. code-block:: python
-
- >>> 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
---------
-
-* Full support for
- `Draft 3 <https://python-jsonschema.readthedocs.org/en/latest/validate/#jsonschema.Draft3Validator>`_
- **and** `Draft 4 <https://python-jsonschema.readthedocs.org/en/latest/validate/#jsonschema.Draft4Validator>`_
- of the schema.
-
-* `Lazy validation <https://python-jsonschema.readthedocs.org/en/latest/validate/#jsonschema.IValidator.iter_errors>`_
- that can iteratively report *all* validation errors.
-
-* Small and extensible
-
-* `Programmatic querying <https://python-jsonschema.readthedocs.org/en/latest/errors/#module-jsonschema>`_
- of which properties or items failed validation.
-
-
-Release Notes
--------------
-
-Version 2.5.0 is mainly a performance release. The interface for `RefResolver`
-was extended to add methods that improve performance on CPython.
-
-Support for custom `RefResolver` objects with the legacy interface should *not*
-be affected. If you notice something amiss please file an issue ticket.
-
-
-Running the Test Suite
-----------------------
-
-If you have ``tox`` installed (perhaps via ``pip install tox`` or your
-package manager), running``tox`` in the directory of your source checkout will
-run ``jsonschema``'s test suite on all of the versions of Python ``jsonschema``
-supports. Note that you'll need to have all of those versions installed in
-order to run the tests on each of them, otherwise ``tox`` will skip (and fail)
-the tests on that version.
-
-Of course you're also free to just run the tests on a single version with your
-favorite test runner. The tests live in the ``jsonschema.tests`` package.
-
-
-Community
----------
-
-There's a `mailing list <https://groups.google.com/forum/#!forum/jsonschema>`_
-for this implementation on Google Groups.
-
-Please join, and feel free to send questions there.
