Mate is a tag-based, event-driven Flex framework.
Flex applications are event-driven. Mate framework has been created to make it easy to handle the events your Flex application creates. Mate allows you to define who is handling those events, whether data needs to be retrieved from the server, or other events need to be triggered.
The Mate framework has the idea of an Event Map to organize events in a central location. Larger applications with multiple function sets can have multiple event maps.
