Zope is a powerful Python web application platform for rapidly and collaboratively developing complex web applications. With version 3, Zope has been rebuilt on top of a Component Architecture that combines the best ideas available from modern web platforms. This new edition details all the changes and new features in Zope 3. It also makes it easier to get started with Zope, incorporating input and suggestions from Zope 3 experts and newcomers alike. In addition, the book addresses the needs of Zope 2 developers who want to use Zope 3 features as they are backported into the Zope 2 platform. The book introduces the key concepts of Zope and its Component Architecture. Each of Zope's capabilities is demonstrated by first building a sample application and then extending it with the addition of more features. The author is a developer of Zope 3 and has been continually contributing to Zope and related projects.
