....by mechanisms of social order and created by more or less autonomous actors to achieve common goals. Because of the proactive and autonomous behaviour of agents it is natural to design organisation systems using agent societies that mimic the behaviour and structure of human organisations [22]. Agent societies represent the interactions between agents and are as such the virtual counterpart of real life societies and organisations. Agents model specific roles in the society and interact with others as a means to accomplish their goals. This perspective makes the design of the system ....

....higher level organisational abstractions, like jobs, organisational structures, norms, social laws or organic rules, useful for the complex task of modelling an agent society. Others, although they do make contributions in this respect [6] are not very suited for application in open environments [7]. Recently, there has been an increasingly widespread trend towards developing organisational abstractions that can be used to view multi agent systems as open organisations. The social metaphor and role based models have started to be generally accepted as a natural way of conceiving multi agent ....

....these advances are fairly recent, some initial suggestions on how to incorporate these concepts into current multiagent systems methodologies have been put forth. For instance, there is a proposal to modify the Gaia methodology to incorporate the notion of social laws and coordination media [14]. Unfortunately, these proposals are still at a high level and do not provide concrete guidance on how to use existing analysis In data centered approaches, entities interact by exchanging data via a shared data space, which determines how data is stored, accessed and consumed, but has ....

....context cannot be simply considered as the place in which coordination act ivities occur, but it is also an active context, capable of enacting specific local coordination laws to rule and support the agents coordination activities. By assuming an organizational (or social) perspective [ZamJW00, Zam01], one can consider the interaction context in terms of an organizational (or social) context. In other words, one must consider that an agent, by entering via a movement an interaction context, enters a foreign organization (society) where specific organizational rules (or social conventions) are ....

....to changes in the environment and of executing in a proactive way, represents a useful paradigm to deal with the complexities of Internet applications. On the one hand, the agent abstraction enables to more naturally deal with the intrinsic dynamics and unpredictability of the Internet environment [21]. On the other hand, agents represent independent and encapsulated loci of control in application, and this can simplify the design and development of complex and large multicomponent applications [9] To some extent, agents can be considered as an evolutionary step towards encapsulation of ....

Finally, agents that are part of a specific multi agent application may require their coordination activities to occur according to specific application needs, despite the different characteristics of the Internet sites where they execute and constraints there imposed [21]. To face the above problems within a uniform framework, we propose modeling the Internet as a multiplicity of local interaction contexts, representing the logical place in which agent coordination activities occur, which can change depending on the agents movement. Depending on its current ....

....the ambition of introducing a detailed methodology, we can sketch the general guidelines for the identification of intra agent and inter agent issues. These guidelines are coherent with the ones identified in previous works in the area of agent oriented software engineering and methodologies [11, 12]. However, in our framework, the process of designing and deploying a mobile agent application must consider not only the role of application developers but also the one of system administrators. From the point of view of application developers, the design of a mobile agent application can be ....

First, when agents need to access data and services and to coordinate with other agents in a foreign Internet site, they are required to face all the typical problems of open systems and open organizations: heterogeneity of languages and protocols, and opportunistic behavior in interactions [Jen00, Zam01]. Second, each Internet site has its own specific characteristics and may be in need of constraining for security or resource control reasons the behavior of an agent in accessing the local resources and in coordinating with other local agents (in other words, the environment can enact ....

The main idea is to abstract the place in ....

In particular, we believe that organisational rules, organisational structures, and organisational patterns must also play a primary role in the analysis and design of such MASs.

In addition, SODA is the first agent oriented methodology to our knowledge to explicitly take the agent environment into account, and provide engineers with specific abstractions and procedures for the design of agent infrastructures.
