Architecture of New GT

• Application Launcher
• Loads a set of javabeans from an RDF model.
• Allows modifying menus, i18n, etc.
• Is a bit of a pain to handle 'menu change'
  events, like for most recently used menu.
• Viper View Mediator
• Javabean container for ViPER API.
• Adds 'user interaction' methods to keep track of
  things not in API (focus, filters).
