Specifying Policies Using UML Sequence Diagrams--An Evaluation Based on a Case Study

Abstract

This paper provides a case study based evaluation of UML sequence diagrams as a notation for policy specification. Policy rules are defined on the basis of deontic logic and provided a trace based semantics interpreted over Kripke structures. This gives a semantics comparable to the UML trace semantics for sequence diagrams, which is utilized in the evaluation. The focus is on requirements with respect to expressivity, utility and human readability.
