One of my favorite new features in Plone 3 is the content rules engine. It allows integrators and site administrators to set rules for triggering actions based on Zope events and conditions. It is really powerful ! Common rules can be used out-of-the-box by simple configuration. Developers can also extend the system with new rules and actions for things such as automatic creation of "pre-defined" content. Using real-world "live" examples, we will go through a tutorial on defining rules for helping content managers. Attendees will be able to think about many use cases (or rethink them) in the perspective of the rules engine's service. They will see how to answer to these use cases either by using an existing rule component or by developing a new one.
