Zope is a web application server and content management system written in Python. It was first released in 1998 and has since become a popular tool for building complex web applications and managing content. Zope is built on top of the Zope Object Database (ZODB), which is an object-oriented database that stores objects as Python objects, rather than in a traditional relational database.

One of the key features of Zope is its ability to manage content using a hierarchical object-oriented system. This means that content can be organized into a tree-like structure, with each node in the tree representing a piece of content. This makes it easy to manage large amounts of content and to control the access to different parts of the system. Zope also provides a powerful set of tools for managing content, including support for versioning, workflow, and publishing.

Another important aspect of Zope is its support for web application development. Zope provides a flexible and extensible architecture that allows developers to build web applications using a variety of technologies, including Python, HTML, JavaScript, and CSS. Zope also provides a powerful set of APIs for accessing and manipulating content, as well as a set of tools for building custom applications and integrating with other systems.

Zope has a large and active community of developers who contribute to the project and provide support to other users. The community maintains a large collection of add-ons and extensions that can be used to extend the functionality of the system, as well as comprehensive documentation and support forums. Zope is a mature and stable platform that is well-suited for building complex web applications and managing content.
