OCL is used to add rigour to UML/MOF models, and in particular can be used to express behavioural details (e.g., operation pre- and postconditions, class invariants) of such models. The applicability and utility of OCL can be assessed by applying it to realistic applications and by investigating its capabilities both in terms of language characteristics and tool support. With this in mind, in this paper we model functional requirements for the Mondex Smart Card Application using UML Diagrams, demonstrate how system invariants as well as operation pre- and post-conditions are specified in OCL, and explore the degree to which OCL tool support can be used to create and validate these models. Moreover, we discuss how these pre- and post-conditions can be validated, in part by discussing how test cases can be selected from the OCL specifications created.
