Zope is a powerful Python web application platform for developing complex web applications rapidly and collaboratively. Zope 2, especially in combination with the Content Management Framework (CMF), has been the basis of several successful open source content management systems such as Plone. With version 3, Zope has been rebuilt on top of a Component Architecture that combines the best ideas available from modern web platforms.

This book focuses on Zope 3, though it also addresses the needs of Zope 2 developers who want to use Zope 3 features as they are backported into the Zope 2 platform. First, the key concepts of Zope and its Component Architecture are introduced. Each of Zope's capabilities is demonstrated by building a sample application and then extending it with more features. The book is targeted towards all developers familiar with web technologies such as HTTP, (X)HTML and XML, and Zope's implementation language itself: Python.

Now in its second edition, the book has been overhauled completely. It has been adapted to the changes and new features in Zope 3 since its first release. The new edition also makes it easier to get started with Zope, incorporating input and suggestions from Zope 3 experts and newcomers alike.

Autorentext

The author's computer programming started out as a hobby and became a profession very quickly. He has been a web developer for many years, having opened his own business during high school already. He started his first Zope project almost half a decade ago and has successfully used Zope in innumerable applications since. A few years ago, when the rewrite of Zope was initiated, he became a developer of Zope 3. He has been continually contributing to Zope and related projects itself since. Currently he is studying Physics at the Dresden University of Technology, while continuing the Internet business.

Zusammenfassung
Where Zope leads, Python follows. So it has been for a decade, and the trend doesn't show any signs of st- ping. Whatever the latest buzzwordbe it RESTful web programming, st- dardized interfaces, pluggable components, or practical restricted-execution environments, Zope has quietly led the way, delivering the goods years ahead of anyone else. Not just as technology concepts, but shipped and working in paying clients' o?ces. And yet, strangely, Zope's role in the ongoing development of Python is little-known and little-appreciated among Python developers. It is f- quently the case that some new and much-touted development in the Python communityespecially in the web application and object security arenasis something that Zope has already been doing for many years. I'm somewhat ba?ed by this peculiar blind spot in the Python com- nity. Even when I tell people that Zope's already done something that they're working on, the response is usually a blank look, or no response at all. It's almost as if the innovations of Zope don't really exist until somebody else reinvents them. In fact, the pattern has led me coin this little saying: Those who do not study Zope, are condemned to reinvent it. It doesn't matter if you don't plan to actually use Zope. Frankly, I haven't used Zope in years. But the lessons I learned from Zope, I use constantly. Studying ZopeZope 3 in particularwill make you a better programmer, without question.
