You can use deftemplate inheritance.
(deftemplate foo (slot A))
(deftemplate bar extends foo (slot B))
(defrule test-rule
(foo (A 1)) ;; matches (foo (A 1)) and (bar (A 1) (B 2))
(bar (A 1) (B 2)) ;; matches only (bar (A 1) (B 2))
=> ...
The important thing to note is that when you define a new deftemplate
with new slots, all the old rules still work for facts of the new
subtype.
