Environment and Agreement Technologies

The notion of Multi-Agent System (MAS) environment, as remarked by recent literature, has gained a key role, becoming a mediating entity, functioning as enabler but possibly also as a manager and constrainer of agent actions, perceptions, and interactions1 while addressing the requirements of openness and scalability. According to such a perspective, the environment is not a merely passive source of agent perceptions and target of agent actions which is, actually, the dominant perspective in agency, but a first-class abstraction that can be suitably designed to encapsulate some fundamental functionalities and services, such as coordination and organization, besides agent mobility, communications, security, etc [2]. Then, the environment dimension appears to intersect with all the dimensions that should be addressed to define an agreement between autonomous agents, that is, all the di erent Agreement Technologies giving support to the building, development and management of agreements in decentralized and open systems between autonomous agents. Those dimensions are the ones related to the development of technologies dealing with: Semantics, Norms, Organizations, Argumentation & Negotiation, and Trust. Though some works have already been done on the connections between environment and organizations or norms, the links and interactions of the environment with the other dimensions of these agreement technologies are still to be explored.
