This section gives the highlights of the implementation for both the Metis framework and the AFE suite used to demonstrate it. The discussion of the Metis framework implementation will be restricted to the workspace implementation and the service access interfaces, i.e., the VEMInterface and the DirectoryInterface implementations, along with important utility objects that are used. The discussion of the AFE implementations will center on what specifically was done to integrate the applications into the thin-client programming model. Overall, the Metis framework is about 7000 lines of Java code.
