Odin
####

Odin provides a declarative framework for defining resources (classes) and their relationships, validation of the fields
that make up the resources and mapping between objects (either a resource, or other python structures).

Odin also comes with built in serialisation tools for importing and exporting data from resources.

Highlights
**********

* Class based declarative style
* Fields for building composite resources
* Field and Resource level validation
* Mapping between resources or extended to other object types (eg Django Models)
* Easy extension to support custom fields
* Python 2.6 :sup:`1`, Python 2.7+, Python 3.3+ and PyPy :sup:`1` supported
* Integration with Django (see `baldr <https://github.com/python-odin/baldr>`_)
* Support for documenting resources with `Sphinx <http://sphinx-doc.org/>`_
* Minimal dependencies (base functionality only requires *six*)

:sup:`1` certain contrib items are not supported. Pint is not installable with PyPy.

Upcoming features
*****************

**In development**

* XML Codec (export completed)
* Complete documentation coverage
* Improvements for CSV Codec (writing, reading multi resource CSV's)
* RESTful interface with support for Flask and Django
* Integration with other libraries (ie `Django <https://www.djangoproject.com/>`_ Models/Forms)
* Integration with SQLAlchemy


Requires
********

* six

**Optional**

* simplejson - Odin will use simplejson if it is available or fallback to the builtin json library
* msgpack-python - To enable use of the msgpack codec
* pyyaml - To enable use of the YAML codec

**Contrib**

* jinja2 >= 2.7 - For documentation generation
* pint - Support for physical quantities using the `Pint <http://pint.readthedocs.org/>`_ library.

**Development**

* pytest - Testing
* pytest-cov - Coverage reporting

Example
*******

**With definition**::

    import odin

    class Author(odin.Resource):
        name = odin.StringField()

    class Publisher(odin.Resource):
        name = odin.StringField()

    class Book(odin.Resource):
        title = odin.StringField()
        authors = odin.ArrayOf(Author)
        publisher = odin.DictAs(Publisher)
        genre = odin.StringField()
        num_pages = odin.IntegerField()

::

    >>> b = Book(
            title="Consider Phlebas",
            genre="Space Opera",
            publisher=Publisher(name="Macmillan"),
            num_pages=471
        )
    >>> b.authors.append(Author(name="Iain M. Banks"))
    >>> from odin.codecs import json_codec
    >>> json_codec.dumps(b, indent=4)
    {
        "$": "Book",
        "authors": [
            {
                "$": "Author",
                "name": "Iain M. Banks"
            }
        ],
        "genre": "Space Opera",
        "num_pages": 471,
        "publisher": {
            "$": "Publisher",
            "name": "Macmillan"
        },
        "title": "Consider Phlebas"
    }

Special Mention
***************

I would like to acknowledge the strong influence on the design of Odin Resources from the Django ORM and it's notable
contributor Malcolm Tredinnick. He was a valued colleague who's untimely passing left a large void in our company and
the wider community.
