Compliance with such regu-lations requires identification of conflicting interpretations of regulatory conditions. Current software engineering methods extract software requirements by converting legal text into semiformal constraints and rules. In this paper we complement these methods with a state-based model that includes all possibilities of information flow. We show that such a model provides a foundation for the interpretation process.展开更多
