Commitment-based Agent Interaction in JaCaMo+

We present the JaCaMo+ framework for programming multiagent systems (MAS), where agents interact thanks to commitment-based interaction protocols. Commitment protocols are realized as artifacts that maintain a social state and notify to the participating agents those events that are relevant to the interaction. We discuss the advantages, like increased modularity and flexibility, that are brought by commitment-ruled interactions with respect to other proposals. We trace back such advantages to the possibility of relying on a standardized commitment lifecycle. We explain how to use the framework to program interacting agents by using the Netbill protocol as running example, and the Gold Miners scenario as a more complex programming example.
