General Architecture
The XMI 2.1 interface used to import XMI files from Enterprise Architect®, Visual Paradigm®, and so on. The Meta Model used to represent all elements contained in the XMI file. The UML Virtual Machine to simulate behavior through message sending. On the top of the UML Virtual Machine it has a Graphical Environment for prototyping and simulation. The default web prototype is done automatically (after the XMI installation). And it has a Customization Framework that combines the Simulation Framework and Simulation Environment to achieve customization through method implementations and drag & drop operations.
