Drools 5.0 is now split into 4 modules, the links below provide more information and screenshots for each module:
Guvnor is our web based governance system, traditionally referred to in the rules world as a BRMS. We decided to move away from the term BRMS to something based on governance, as our long term emphasis is no longer rules specific. Expert is the traditional rules engine. Fusion is the event processing side, it's a play on data/sensor fusion terminology. Finally there is Flow which is our workflow module.
