I think what you are looking for are "defmodules." This is a planned
feature for Jess 6.0 final.
For now, the alternatives are 1) separate Rete objects, each with
their own rule base, or 2) control facts. The latter definitely
doesn't help simplify the rule base -- on the contrary, it tends to
make it worse.
