Integration of UML and B specification techniques: systematic transformation from OCL expressions into B

Abstract

In the continuity of our research on integration of UML and B, we address the transformation from OCL (Object Constraint Language), which is an integral part of UML, into B. Our derivation schemes allow to systematically even automatically derive into B not only the complementary class invariants, the statechart guard conditions, but also the OCL specification for UML operations.
