It's a JSON validation and "post-parsing" library for Python.
It's an attempt to make conversion of complex JSON objects to native, meaningful Python objects, and back again easy to do robustly.
This will hopefully make it easier to write JSON APIs that have really stellar error handling.
This library was written by me (steinarvk@) while an employee of Google. Due to various legal intricacies, Google claims copyright to the code. The code is open sourced under the Apache 2 license, so this should not be a hindrance to anyone wishing to use the code.
Although contributions are very welcome, there are unfortunately some legal hoops to jump through if you wish to contribute. See CONTRIBUTING.md for details.
This code was written in my spare time. It is in no sense an official Google product, or even an unofficial one.
