FSL – Fibred Security Language

Authors: Valerio Genovese, Dov M. Gabbay, Guido Boella, and Leendert van der Torre

Published in: Dagstuhl Seminar Proceedings, Volume 9121, Normative Multi-Agent Systems (2009)

Abstract
We develop a fibred security language capable to express statements of the form begin{center} ${x }varphi (x) says psi$ end{center} where ${x}varphi (x)$ is the set of all $x$ that satisfy $varphi$ and $psi$ is any formula. $varphi$ and $psi$ may share several free variables. For example, we can express the following: "A member $m$ of the Program Committee can not accept a paper $P_1$ in which one of its authors says that he has published a paper with him after 2007" begin{center} $ eg({m} [PC(m) wedge {y}author\_of(y,P_1) extbf{ says } exists p(paper(p) wedge author\_of(m,p) wedge author\_of(y,p) wedge year(p) geq 2007)] extbf{ says } accept(P_1))$ end{center}

Adding Organizations and Roles as Primitives to the JADE Framework

Authors: Roberto Grenna, Matteo Baldoni, Guido Boella, Leendert van der Torre, Mauro Dorni, Andrea Mugnaini, and Valerio Genovese

Published in: Dagstuhl Seminar Proceedings, Volume 8361, Programming Multi-Agent Systems (2008)

Abstract
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.

Towards a General Framework for Modelling Roles

Authors: Valerio Genovese

Published in: Dagstuhl Seminar Proceedings, Volume 7122, Normative Multi-agent Systems (2007)

Abstract
Role is a widespread concept, it is used in many areas like MAS, Programming Languages, Organizations, Security and OO mod- elling. Unfortunately, it seems that the literature is not actually able to give a uniform definition of roles, there exist several approaches that model roles in many different (or even opposite) ways. In this draft we start to define a meta-model for roles. Our aim is to build a formal framework through which we can describe different roles appeared in the literature or implemented in up and running computer systems. In particular we give a new definition of role’s foundation introducing ses- sions, which are a formal instrument to talk about role’s states and we show how sessions may be useful to model many different role’s accounts.
