Conversation oriented programming for agent interaction

Conversations are an agent programming abstraction intended to represent mo dels of interaction among agents and to support the execution of these mode ls in multi-agent environments. In this paper we review a conversational co ordination language we have designed and used in the past few years, to cha racterize its main assumptions, strengths and limitations. Based on this an alysis we discuss a number of major new features and extensions for our nex t generation conversational coordination language.
