Adding Organizations and Roles as Primitives to the JADE Framework

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 primitives to program in Java organizations structured in roles and to enable agents to play roles in organizations. Roles facilitate the coordination of agents inside an organization and give new abilities in the context of organizations, called powers, to the agents which satisfy the requirements necessary to play the roles. As primitives to program organizations and roles we provide classes and protocols which enable an agent to enact a new role in an organization and to interact with the role by invoking the execution of powers, and to receive new goals to be fulfilled. Roles have state and behaviour, thus, they are instances of classes and are strictly connected with the organization offering them. Since roles and organizations can be on a different platform with respect to the role player, the communication with them happens via protocols. Moreover, since, besides using protocols, roles and organizations can have complex behaviours, they are implemented by extending the JADE agent class

Design and implementation of a FIPA based agent communication model for a logic programming framework

In this paper we consider the design of an agent communication model based on the FIPA Architecture and FIPA Interaction Protocols. Our goal is to allow the agents to reach each other by their characteristics and to exchange messages using a standard Agent Communication Language. We propose the design and implementation of a framework as an extension of Prolog, following the spirit of Logic Programming. In our framework, the agents are allowed to register themselves in MASs in order to allow other agents to locate them easily. The agents may search for agents having specific characteristics, or providing determined services in order to interact with them.Red de Universidades con Carreras en Informática (RedUNCI

Social Relationships for Designing Agent Interaction in JADE

Abstract—Current agent platforms do not provide agents the means for reasoning about expected behaviours during interactions. This lack is due to the absence of design primitives to explicitly shape interaction patterns as first-class resources. This work presents 2COMM4JADE, a framework based on JADE and CArtAgO platforms that allows definition of social relationships among parties, represented by social commitments, decoupled from the agent design itself.

Programming JADE and Jason Agents Based on Social Relationships Using a Uniform Approach

Abstract. Interaction is an essential feature in multiagent systems. De-sign primitives are needed to explicitly model desired patterns. This work presents 2COMM as a framework for defining social relations among parties, represented by social commitments. Starting from the definition of interaction protocols, 2COMM allows to decouple interaction design from agent design. Currently, adapters were developed for allowing the use of 2COMM with the JADE and the JaCaMo platforms. We show how agents for the two platforms can be implemented by relying on a common programming schema

ReSpecTX: Programming Interaction Made Easy

In this paper we present the ReSpecTX language, toolchain, and standard library as a first step of a path aimed at closing the gap between coordination languages \u2013 mostly a prerogative of the academic realm until now \u2013 and their industrial counterparts. Since the limited adoption of coordination languages within the industrial realm is also due to the lack of suitable toolchains and libraries of reusable mechanisms, ReSpecTX equips a core coordination language (ReSpecT) with tools and features commonly found in mainstream programming languages. In particular, ReSpecTX makes it possible to provide a reference library of reusable and composable interaction patterns

Autonomic Protocol-based Coordination in Dynamic Inter-Organizational Workflow

International audienceGiven the maturity of Internet standards, inter-organizational workflow is expected to be deployed in environments that are more dynamic and open than before. This paper addresses Inter Organizational Workflow (IOW) coordination in such a context, mainly investigating autonomic coordination managed at run-time. It is based on the idea that an agent-based approach is suitable to deal with this issue. More precisely, this paper introduces a framework for dynamic IOW in which involved processes are encapsulated into agents, called Process Agents (PA) in order to give them the capability to autonomously decide with whom, when and how to cooperate, and in which involved processes can access protocol components for their coordination needs. Our approach is based on the capability of PAs in playing different coordination protocols in order to take part in new business opportunities. This solution has numerous advantages. First, it provides extendable and reusable coordination components. Then, it supports run-time protocol integration. Finally, it eases openness since it imposes very few constraints
