Hi All
I am an avid user of ZEN for over 10 years now and it works for me.
But it seems that Intersystems are no longer actively developing it (or ZEN Mojo), the only published reference to this is here
Zen is a school of Mahayana Buddhism that originated in China during the Tang dynasty as Zen Buddhism. Zen school was strongly influenced by Taoism and developed as a distinct school of Chinese Buddhism.
In InterSystems Data Platform Zen is a name for MVC web application framework for rapid software development.
