The OpenNARS implementation is modularized, with plugins communicating via an event system. The following is a brief description of the events that can be subsribed to in the OpenNARS framework. The code defining the event types can be found org.opennars.io.events TODO-Here-link.

• CyclesEnd - fired at the end of each Nar multi-cycle execution
• CycleStart - fired at the beginning of each memory cycle
• CycleEnd - fired at the end of each memory cycle
• WorkCycleStart - fired at the beginning of each individual Memory work cycle
• WorkCycleEnd - fired at the end of each Memory individual cycle
• ResetStart - called before memory.reset() proceeds
