As u might guessed I'm working with a bigger model where room and
thermometer is just part of.
I cannot just throw some of it away and create it anew.
What I really like to know is if drools can handle object trees not just
facts.
Do I have to build another model just to keep my actual model in synch with
drools?
Is it too hard to tell?
