Figure 2.11 KnowledgeWorks System Browser
If you are familiar with LispWorks system definitions, look at the system definition for the animal demo in the Editor tool by choosing
File > Open...
and navigating to the file
examples/kw/animal/defsystem.lisp
. It contains a
KB-SYSTEM
and a
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
.
KB-SYSTEM
s are reloaded when the rules are cleared.
KB-INIT-SYSTEM
s 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.
