Choice, Interoperability, and Conformance in Interaction Protocols and Service Choreographies

Free registration required

Executive Summary

Many real-world applications of multiagent systems require independently designed (Heterogeneous) and operated (Autonomous) agents to interoperate. The authors consider agents who offer business services and collaborate in interesting business service engagements. They formalize notions of interoperability and conformance, which appropriately support agent heterogeneity and autonomy. With respect to autonomy, the approach considers the choices that each agent has, and how their choices are coordinated so that at any time one agent leads and its counterpart follows, but with initiative fluidly shifting among the participants. With respect to heterogeneity, they characterize the variations in the agents' designs, and show how an agent may conform to a specification or substitute for another agent.
