Partial JSON API implementation in Python on top of Schematics

Hyp
===
JSON-API responses in Python.

About
-----
Hyp is a library implementing the _must_ parts of the [JSON-API](http://jsonapi.org) response specification. This means that you can use Hyp to serialize your models into responses that contain links and linked compound documents. It works really good in combination with some micro web framework of choice, preferably [Flask](http://flask.pocoo.org).

It is built on top of [Schematics](https://schematics.readthedocs.org/en/latest/) in the sense that Schematics is used for data serialization and that Hyp handles the rest. To add support for other data serialization libraries such as [Colander](http://docs.pylonsproject.org/projects/colander/en/latest/) should be trivial though.

Tutorial
--------

First let's define some serializers for your models:

```python
from schematics.models import Model
from schematics.types import IntType, StringType


class CommentSerializer(Model):
id = IntType()
content = StringType()


class PersonSerializer(Model):
id = IntType()
name = StringType()


class PostSerializer(Model):
id = IntType()
title = StringType()
```

We can then create our own responders using the `hyp.Responders` class:

```python
from hyp.responder import Responder


class CommentResponder(Responder):
TYPE = 'comment'
SERIALIZER = CommentSerializer


class PersonResponder(Responder):
TYPE = 'person'
SERIALIZER = PersonSerializer


class PostResponder(Responder):
TYPE = 'post'
SERIALIZER = PostSerializer
LINKS = {
'comments': {
'responder': CommentResponder(),
'href': 'http://example.com/comments/{posts.comments}',
},
'author': {
'responder': PersonResponder(),
'href': 'http://example.com/people/{posts.author}',
},
}
```

Finally we can use our responders for creating responses. These responses goes perfectly into any Flask application out there:

```python
post = {
'id': 1,
'title': 'My post',
'comments': [
{'id': 1, 'content': 'A comment'},
{'id': 2, 'content': 'Another comment'},
]
}

json = PostResponder().respond(post, linked={'comments': comments})

```

The `json` variable will now contain some freshly squeezed json ready for sending back to the client:

```json

{
"posts": [
{
"id": 1,
"title": "My title",
"links": {
"comments": [1, 2]
}
}
],
"linked": {
"comments": [
{
"id": 1,
"content": "My comment"
},
{
"id": 2,
"content": "Another comment"
}
]
},
"links": {
"posts.comments": {
"type": "comments",
"href": "http://example.com/comments/{posts.comments}"
}
}
}
```
