Easiest thing is to look at the code: https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/java/org/drools/core/beliefsystem/defeasible/DefeasibleBeliefSet.java https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/java/org/drools/core/beliefsystem/defeasible/DefeasibleBeliefSystem.java
And tests: https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/compiler/beliefsystem/defeasible/DefeasibilityTest.java As Davide said, this is highly experimental. It’s likely we won’t use a ‘neg’ entry point in the future to handle negated facts, but instead provided a meta property.
