Introduction

JADE offers a graphical interface to the DF (Directory Facilitator) agent.
This GUI allows to federate with other DFs and to control (i.e. register, deregister, modify and search for agent descriptions) all the network of federated DFs. The GUI and the code of the DF itself can be reused to implement user-defined DF, as shown in the example subdf that is part of the JADE examples.
The DF provides "yellow pages" services to other agents. Agents may register their services with the DF or query the DF to find out what services are offered by which agents. At least one DF must be resident on each Agent Platform (the default DF). However an AP may support any number of DF's. DF's can register with each other building a federation of DF's. 
 
 

Starting the DF GUI

It is possible to start the DF GUI that allows to interact with the DF agent, from the Tools menubar of the RMA GUI.

The figure below shows the GUI of the DF.
