I don't understand you. The two approaches ((A)generating Java classes
with bean accessors from Protege classes or (B) directly converting
Protege classes and instances into Jess templates and facts) are
equivalent in terms of performing operations on RHS of Jess rules and
for preserving the Protege knowledge structures. The two differ in terms
of (1) your ability to attach methods to Protege classes (strength of
A)(2) the ability to modify your classes dynamically and have that
reflected in Jess (strength of B).
