The organization metaphor is often used in the design and implementation of multiagent systems. However, few agent programming languages provide facilities to define them. Several frameworks are proposed to coordinate MAS with organizations, but they are not programmable with general purpose languages. In this paper we extend the JADE framework with(More)
In this paper we generalize and merge two models of roles used in multiagent systems which address complementary aspects: enacting roles and communication among roles in an organization or institution. We do this by proposing a metamodel of roles and specializing the metamodel to fit two existing models. We show how the two approaches can be integrated(More)
Organizations are the subject of many recent papers in the MAS field, and also among the topics of workshops like COIN, AOSE, CoOrg and NorMAS. They are used for coordinating open multiagent systems, providing control of access rights, enabling the accommodation of heterogeneous agents, and providing suitable abstractions to model real world institutions(More)
extension which provides the instructions to manage roles. After defined the environment in which we have worked, we will discuss the language's new instructions and we will show an example. Object orientation is a leading paradigm in programming languages, modeling, knowledge representation and databases. When we think to an object, we do it in terms of(More)

In this paper we apply the powerJava model of roles and relationships to a web application programming environment. First we show how the notion of role, as defined in powerJava, combines and automates several aspects which are important in web application programming, and which are now unrelated and dealt with separately and mostly by hand, and thus prone(More)
Organizations and roles are often seen as mental constructs, good to be used during the design phase in Multi Agent Systems, but they have also been considered as first class citizens in MAS, when objective coordination is needed. Roles facilitate the coordination of agents inside an organization, and they give new abilities in the context of organizations,(More)
