Zope Wikipedia. This article is about an application server platform. For the fish known as Zope, see Abramis ballerus. Zope is a community project concerned with a free and open source, object orientedwebapplication server written in the Pythonprogramming language. Zope stands for Z Object Publishing Environment, and was the first system using the now common object publishing methodology for the Web. Zope has been recognized as a Pythonkiller app, an application that helped put Python in the spotlight. Over the last few years, the Zope community has spawned several additional web frameworks with disparate aims and principles, but sharing philosophy, people, and source code.

Blue. Bream earlier called Zope 3 is less widespread but underlies several large sites, including Launchpad. Grok was started as a more programmer friendly framework, Zope 3 for cavemen, and in 2. Pyramid ex BFG gained popularity in the Zope community as a minimalistic framework based on Zope principles. HistoryeditThe Zope Corporation was formed in 1. Fredericksburg, Virginia under the name Digital Creations, as a joint venture with Infi. Net a joint newspaper chain venture. The company developed a classified advertisement engine for the Internet. In 1. 99. 7, the company became independently owned and private. The companys software engineers are led by CTO Jim Fulton. Python. Labs, creators of Python, became part of the company in the year 2. Python founder Guido van Rossum left Zope Corp in 2. What is now known as Zope 2 began with the merging of three separate software products Bobo, Document Template, and Bobo. POS into the Principia application server. At the behest of its largest investor, Opticality Ventures, Principia was re released as free software under the name Zope in 1. Bobo, and therefore Zope, was the first Web object publishing solution. In November 2. Zope 3 was released. Zope 3 is a complete rewrite that preserves only the original ZODB object database. It is directly intended for enterprise Web application development using the newest development paradigms. Zope 3 is, however, not compatible with Zope 2, so you cannot run Zope 2 applications on Zope 3. It was originally intended to introduce a backwards compatibility layer so that Zope 2 software would run on Zope 3. Instead a module known as Five introduced the new Zope 3 paradigms into Zope 2, although full compatibility isnt possible that way either. The existence of two incompatible Web frameworks called Zope has caused a lot of confusion. In response, in January 2. Zope 3 was renamed Blue. Bream. 67 Zope and blue bream are names of a kind of fish, ballerus ballerus. Zope FoundationeditThe Zope Foundation is an organization that promotes the development of the Zope platform by supporting the community that develops and maintains the relevant software components. The community includes both open source software, documentation and web infrastructure contributors, as well as business and organization consumers of the software platform. It manages the zope. A Zope website is usually composed of objects in a Zope Object Database, not files on a file system, as is usual with most web servers. This allows users to harness the advantages of object technologies, such as encapsulation. Zope maps URLs to objects using the containment hierarchy of such objects methods are considered to be contained in their objects as well. Data can be stored in other databases as well, or on the file system, but ZODB is the most common solution. Zope provides two mechanisms for HTML templating Document Template Markup Language DTML and Zope Page Templates ZPT. DTML is a tag based language that allows implementation of simple scripting in the templates. DTML has provisions for variable inclusion, conditions, and loops. However, DTML can be problematic DTML tags interspersed with HTML form non valid HTML documents, and its use requires care when including logic into templates, to retain code readability. The use of DTML is discouraged by many leading Zope developers. ZPT is a technology that addresses the shortcomings of DTML. ZPT templates can be either well formed XML documents or HTML documents, in which all special markup is presented as attributes in the TAL Template Attribute Language namespace. ZPT offers a very limited set of tools for conditional inclusion and repetition of XML elements. Consequently, the templates are usually quite simple, with most logic implemented in Python code. One significant advantage of ZPT templates is that they can be edited in most graphical HTML editors. ZPT also offers direct support for internationalization. Zope 2 underlies the Plonecontent management system, as well as the ERP5 open source enterprise resource planning system. Blue. BreameditBlue. Bream is a rewrite by the Zope developers of the Zope 2 web application server. It was created under the name Zope 3, but the existence of two incompatible frameworks with the same name caused much confusion, and Zope 3 was renamed Blue. Bream in January 2. Blue. Bream is distributed under the terms of the Zope Public License1. Zope 2 has proven itself as a useful framework for Web applications development, but its use revealed some shortcomings. To name a few, creating Zope 2 products involves copying a lot of boilerplate code magic code that just has to be there, and the built in management interface is difficult to modify or replace. Zope 3 was a rewrite of the software that attempts to address these shortcomings while retaining the advantages of Zope that led to its popularity. Blue. Bream is based on a component architecture1. Python. Although originally intended as a replacement for Zope 2, the Zope Component Architecture has instead been backported to Zope 2, starting with Zope 2. Many Zope platforms such as Plone are going through the same type of piece by piece rewriting. The first production release of the new software, Zope X3 3. November 6, 2. 00. HistoryeditThe Zope 3 project started in February 2. Zope as an almost complete rewrite, with the goal to retain the successful features of Zope 2 while trying to fix some of its shortcomings. The goal was to create a more developer friendly and flexible platform for programming web applications than Zope 2 is. Harry E Sally Feitos Um Para O Outro. The project began with the development of a component architecture, which allows the structuring of code into small, composable units with introspectable interfaces. The interfaces are supported by an interface package in order to provide the functionality of explicitly declared interfaces to the Python language. The first production release of the software, Zope X3, was released on November 6, 2. In January 2. 01. Zope 3 was renamed Blue. Bream. 9TechnologyeditThe goal of the project was to enable programmers to use Zope in order to expose arbitrary Python objects as model objects to the web without the need to make these objects fulfill particular behavior requirements. In Zope 2 there had been many behavior requirements to allow objects to participate in the framework, which resulted in a large amount of mixin base classes and special attributes. Blue. Bream uses a modelview architecture, separating the presentation code from the problem domain code. Views and models are linked together by the component architecture.
