Every schema is an interface and specifies the public fields of an object. A field roughly corresponds to an attribute of a python object. But a Field provides space for at least a title and a description. It can also constrain its value and provide a validation method. Besides you can optionally specify characteristics such as its value being read-only or not required. This package is intended to be independently reusable in any Python project. It is maintained by the Zope Toolkit project. WWW: http://www.python.org/pypi/zope.schema END
