Zope is a web application server, based around and closely modeling the Python programming language. It's open source and has a very rich development environment that makes it easy for people to develop extensions and enhancements for interfacing to different products and services. Zope is one of those projects that I reluctantly call forgotten. It's not the right term, but with some additional explanation you'll see where I'm coming from. Zope is not, in any way languishing (quite the opposite), but it is a technology and application that people simply use and deploy web sites and applications - often forgetting the significance of the environment in which they are deploying their application.
