PSARC,
I am sponsoring this case for Ghee Teo of the JDS - Gnome
group in Dublin, Ireland. The case directory contains this
proposal. I have set the timeout for Tuesday, February 26th,
2008.
The project proposes to integrate the Python zope interfaces
into a minor release of Solaris. The Zope component architecture
is about how to create reusable components, but not the reusable
components itself. Other Python modules will depend upon the
Zope interface architecture.
Thanks,
John

4. Technical Description:
4.1. Details:
This package provides the python zope Interface module. This module is
part of the Zope 3 project [1] which is to provide Component based
development for web services. However, Zope interface is also used by other
web development framework such as Twisted and it is the primary reason for
delivery of zope interface here.
Interfaces are objects that re-specify the external behavior of objects
that
provides them in the first place. An interface can redefine the behavior of
the original objects through:
- Replacing a string in the the documentation
- Modifying the object's attributes.
- Invariants which is to place conditions that the original objects must
satisfy.
Interface support is an important Object Oriented techniques that allows:
- less patching to the original classes
- Interfaces can be maintained and yet its implementation can be modified
to new requirements.
- modification of GUI without de-stabilizing the applications.
Good examples for how use the zope interface can be found here [2].
