The example ControlH and MetaH architecture specifications shown are screen snapshots of an actual editor window. You can traverse the diagrams reachable from the missile pitch axis controller example by selecting an object of interest in an architecture diagram. If an implementation diagram for an object exists, you will go to that diagram. If you select the context object in the upper left-hand corner, you will go to the parent diagram.
The other portions of the architecture diagram image include buttons and menus that are used to create and edit architecture diagrams. Unfortunately, WWW/Mosaic technology does not yet allow us to provide access to a graphical editor over the network that you can experiment with. What these images do allow you to do is move up and down in a hierarchical architecture specification, just as the actual editor allows you to do, examining some sample ControlH and MetaH architecture specifications.
You may not be able to traverse ControlH and MetaH architecture specifications because your brower does not support image mapping.
