Description of the tool

RoZ (named after the Rosetta stone) is a product of the CHAMPOLLION project whose goal is the integration of formal and semi-formal methods for software development. The tool is integrated in the Rational Rose environment. It allows the integration of data specification expressed in UML with formal annotations in the Z (or Object-Z) language. Starting from an annotated specification, the tool automatically produces a formal specification by translating the UML constructs and merging them with the annotations.

RoZ completes the UML class diagram by automatically generating both UML and Z specifications of elementary operations on the classes (attributes modifications, adding and deleting objects of the class). The tool also allows to record a guard for each operation and can generate corresponding proof obligations to show that guards are consistent with the actual pre-conditions of these operations. The Z-EVES prover (from ORA) can be used to discharge these proof obligations.

In the future, we foresee the following evolutions for the tool: compatibility with other model-based target languages (B, VDM,...), translation of other UML diagrams, verification of several consistency properties, the use of OCL as the annotation language.
