However, a universally accepted standard for ACLs is still missing. Among the different approaches to the definition of ACL semantics, the \textit{social} approach seems the most appropriate to express semantics of communication in open societies of autonomous and heterogeneous agents. In this paper we propose a formalism (\textit{deontic constraints}) to express social ACL semantics, which can be grounded on a computational logic framework, thus allowing automatic verification of compliance by means of appropriate proof procedures. We also show how several common communication performatives can be defined by means of deontic constraints.} }

We propose a model where the society defines the allowed interaction protocols, which determine the ``socially'' allowed agent interaction patterns. The semantics of protocols can be defined by means of social integrity constraints. The main advantages of this approach are in the design of societies of agents, and in the possibility to detect undesirable behavior. In the paper, we present the model for societies ruled by protocols expressed as integrity constraints, and its declarative semantics. A sketch of the operational counterpart is also given.} }
