user interface is used to develop marketplace agents using ontology for discovery. Specifically, it has metadata supports handling of:
* Messages received from other agents that are handled by a MessageHandler;
* Events received from internal components that are handled by an EventHandler;
allow information to persist and be shared across different message and event handlers using patterns
