KnowledgeWorks System Browser
If you are familiar with LispWorks system definitions, look at the system definition for the animal demo, by evaluating:
(example-edit-file "kw/animal/defsystem")
It contains systems with type :kb-system and :kb-init-system. Examine the components of each system (which can be source files or subsystems) using the System Browser which is available from the Editor via Alt+X Describe System or File > Browse Parent System.
Systems with type :kb-system are reloaded when the rules are cleared. Systems with type :kb-init-system are reloaded when the object base is cleared.
Try this out by finding the KnowledgeWorks Listener and choosing Memory > Clear Objects and Rules. Then enter (load-system "ANIMAL") into the KnowledgeWorks Listener to reload the system animal. Both the files animal-rules and animal-objs are reloaded. Now choose KnowledgeWorks > Memory > Clear Objects and reload the animal system again and note how only the file animal-objs is reloaded.
