The current practice in multiagent systems typically associates the environment with resources that are external to agents and their communication infrastructure. Advanced uses of the environment include infrastructures for indirect coordination, such as digital pheromones, or support for governed interaction in electronic institutions. Yet, in general, the(More)
Direct interaction and explicit communication are not always the best approaches for achieving coherent systemic behaviour in the context of Multi-Agent Systems (MAS). This is evident when taking into account recent approaches dealing with environment-based coordination such as stigmergy and, more generally, mediated interaction. In this paper we propose a(More)
The notion of society should play a central role in agent-oriented software engineering as a first-class abstraction around which complex systems can be designed and built as multi-agent systems. We argue that an effective agent-oriented methodology should account for inter-agent aspects by providing engineers with specific abstractions and tools for the(More)
Coordination and access control are related issues in open distributed agent systems, being both concerned with governing interaction between agents and resources. In particular, while coordination deals with enabling interaction and making it fruitful, access control is meant to control interaction to make it harmless. We argue that this twofold facet has(More)
