This application demonstrates defining colander schemas as
through-the-web (TWW) objects, managed in SubstanceD <http://substanced.net>_
Schema definitions are managed as YAML <http://yaml.org>, using the
bindings defined in sweetpotatopie <https://github.com/Pylons/sweetpotatopie/>.

Defining Schemas

In the SubstanceD management interface (SDI), visit the schemas service,
found in the ZODB root. For each content type which should have a TTW schema,
add a TTWSchema object, naming it for the content type (e.g., 'Document').

Edit the 'yaml' property, using the sweetpotatopie documentation <https://github.com/Pylons/sweetpotatopie/blob/master/doc/narrative.rst>_
as a guide. E.g.::

!schema
children:
- !field.string
name: title
- !field.integer
name: rating
- !field.float
name: weight
- !field.decimal
name: price
- !field.boolean
name: active
- !field.datetime
name: expires
- !field.date
name: joined

Associating Schemas with Types

Any type which should use a TTW schema needs (for now) to add a propertysheet
to its SubstanceD @content registration. E.g.::

from candide.property import CandidePropertysheet
from persistent import Persistent
from substanced.content import content

@content(
    'MyType',
    add_view='add_my_type',
    propertysheets = (
        # others...
        ('TTW', CandidePropertysheet), 
    )
)
class MyType(Persistent):
    pass

This package defines a 'Document' type which enables such a propertysheet.
