Hi All-
I am using JessTab and am new to JESS, and would greatly appreciate a nudge in
the right direction. I am trying to do a simple operation, but having no
success.
Given:
Protege class A which contains (among other slots) slot b which is of type
Instance of class C. Class C contains slot cname.
Problem:
How do you write a JessTab rule to fire when a certain class C instance occurs
in class A's slot b?
I've tried (among other things):
(mapclass :THING)
(defrule AbC
(object (is-a A)(b ?x))
?y <- (slot-get ?x cname)
(test (eq ?y "Mike"))
=>
(printout t "Mike exists in class A." crlf))
(run)
; Results in 0 (never fired, though the condition is true)
Many thanks,
Mike Geide
