To extend the Notifications framework to provide new event types or subscription types or UI elements, you create Notifications plug-ins. The Notifications package on drupal.org already includes several plug-ins that provide a set of flexible and configurable subscription types and UI widgets. (See notifications_content.module, included in the Notifications package.)

To build a plug-in, you implement the hooks provided by the Notifications and Messaging frameworks (usually hook_notifications() and hook_messaging()). By implementing these hooks, you won't have to handle low level features, like message templating and sending, queueing, database storage, etc...

NOTE: Contributed plug-ins are welcome. Or, if you are implementing the Notifications API from another module in a published package, let us know so we can link to it from the project main page. Other modules currently using this framework are Organic Groups and Mail to Web.
