Introduction
------------
This project heavily inspired by py-jsonapi_ (author is `Benedikt Schmitt`_).
Some parts of this project is improved and refactored dev-schema_ branch
of **py-jsonapi**. At beginning of aiohttp-json-api_ this branch
was a great, but not finished implementation of JSON API with
*schema controllers*. Also, py-jsonapi_ is not asynchronous and use inside
self-implemented Request/Response classes.
Some of base entities of py-jsonapi_ was replaced with aiohttp_
server's objects, some of it was divided into new separate entities
(e.g. `JSONAPIContext` or `Registry`).
