Experience Optimization cartridge reference
For the triggering of Promotions, Experience Optimization uses Session and Audience Manager cartridges.
Experience Optimization requires the Ambient Data Framework installed and configured as part of your Content Delivery installation for SDL Tridion Sites. The Ambient Data Framework (ADF) is a Content Delivery module that provides a flexible and configurable framework for gathering and transforming website data, such as information about the website visitor and user session.
The framework allows you to program your own Claim Processors using the ADF Java API and organize them into cartridges that plug into the framework to implement specific functionality.
