Objects are asserted into the WorkingMemory, which allows the rule-engine to be aware of its existence, and a fact handle is returned as a reference. Once asserted, the fact may be used to satisfy some portion of any rule's activation condition.

Now we are looking at switching to drools because we cannot bare the overhead of translating between java and prolog the representation of every data element that we pass to prolog. For example, integer numbers in java are represented differently than in prolog and their representation needed to be translated back and forth across the java / prolog interface. Drools seems to handle java objects in its primitive representation (good!). However, we don't know how objects are represented in WorkingMemory. Question: ------------- Is the WorkingMemory keeping its own parallel COPY of the asserted objects or it is only keeping REFERENCES to the actual objects? If the WM is copying (or creating its own representation) of the asserted objects then the drools alternative might not be as attractive as we thought.
