UML is a widespread language used in both industry and academia, despite the fact that its semantics is still informal and allows ambiguities. On the other hand, OhCircus is a formal specification language which unifies Z, CSP, the refinement calculus of Morgan and object-oriented theories. In this work we integrate UML class diagrams and OhCircus by written UML elements in terms of OhCircus constructs. However, instead of a simply syntactical mapping, we also propose the concept of a class model to capture associations and global constraints. Finally, we use this integration to prove the refinement of associations as attributes, a result that relates analysis to design to implementation and which is very common in industry.
