Accountable Objects: Modeling Liability in Open Distributed Systems

As an increasing amount of commercial activity becomes automated, the importance of techniques for providing complete system specifications, checking the correctness of interactions and flagging incorrect behaviour increases.

Abstract

As an increasing amount of commercial activity becomes automated, the importance of techniques for providing complete system specifications, checking the correctness of interactions and flagging incorrect behaviour increases. The aim throughout is to generate more complete information about the system and so to produce IT solutions that reflect the business requirements accurately. So far, most efforts have been placed on the appropriate specification of the system behavior and then on the non-functional requirements that constitute the contract between a system and its users. But in fully-automated commercial systems, such as Cloud Computing or SOA systems, we should also consider the liability of the different parties, since we should be able to assign responsibility to objects and, more importantly, to know in case of problems or contract violations, which one should be blamed.

The consequence of these considerations is that we need the ability to express more directly the necessary obligations and other deontic concepts, such as permissions and prohibitions, giving the designer the tools for extending the behavioural information to make it clear where obligations apply and with what detailed properties. In this talk we describe current activities within the International Organization for Standardization (ISO) to extend the ODP family of standards for the expression of policies using deontic logic, and on how to improve support for deontic concepts based on their reification.
