The CASAA module is the newest evolution of the CMF module.
This module is a whole new experience in terms of mapping your Drupal site via URL paths and taxonomy terms to ad serving and analytics systems such as Google Analytics, Omniture Site Catalyst, Yahoo! APT, and many other systems that sites use to serve ads and measure traffic trends throughout the site. The framework, with this mapping concept, allows admins to provide an even more targeted context base to strengthen control and have an even more precise system for that.
Along with the many features and more robust interface the framework maintains the strong foundation that the CMF provided as well as a special upgrade path for current users of CMF to upgrade to CASAA and still maintain their mappings that they had and not have to re-map their site.
