“…Our method is not the first attempt to provide formal semantics for i* models. For example, Formal Tropos (FT) [5], supports formal verification of i* models through model checking. Also, in the i*-ConGolog approach [19], on which our method is based, SR models are associated with formal ConGolog programs for simulation and verification.…”

Abstract. This paper describes an agent-oriented requirements engineering approach that combines informal i* models with formal specifications in the multiagent system specification formalism CASL. This allows the requirements engineer to exploit the complementary features of the frameworks. i* can be used to model social dependencies between agents and how process design choices affect the agents' goals. CASL can be used to model complex processes formally. We introduce an intermediate notation to support the mapping between i* models and CASL specifications. In the combined i*-CASL framework, agents' goals and knowledge are represented as their mental states, which allows for the formal analysis and verification of, among other things, complex agent interactions and incomplete knowledge. Our models can also serve as high-level specifications for multiagent systems.

“…Goal-oriented languages, such as i* [36] and KAOS [11], and object-oriented notations, such as ADORA [17], include graphical notations to view relationships between entities, such as actors, actions and objects. Because of computational intractability and undecidability of using highly expressive logics [16], RSLs often formalize only a select class of requirements phenomena, e.g., using description logic [5] and various temporal logics, such as interval [26], real-time [11] or linear [14] temporal logic. Consequently, RSLs and RMLs may struggle with the balance between expressivity and readability [13].…”

Information systems are increasingly distributed and pervasive, enabling organizations to deliver remote services and share personal information, worldwide. However, developers face significant challenges in managing the many laws that govern their systems in this multi-jurisdictional environment. In this paper, we report on a computational requirements document expressible using a legal requirements specification language (LRSL). The purpose is to make legal requirements open and available to policy makers, business analysts and software developers, alike. We show how requirements engineers can codify policy and law using the LRSL and design, debug, analyze, trace, and visualize relationships among regulatory requirements. The LRSL provides new constructs for expressing distributed constraints, making regulatory specification patterns visually salient, and enabling metrics to quantitatively measure different styles for writing legal and policy documents. We discovered and validated the LRSL using thirteen U.S. state data breach notification laws.

“…In addition to the KAOS approach, a notable body of work has been developed around the Tropos framework [Cas02,Bre04]. The formalism that underpins formal modelling of goals in Tropos is also based on synchronous state-based temporal logic [Fux04]. Consequently the results and insights described in this paper are likely to be directly applicable to the Tropos framework.…”
