A Formal Mapping between UML Static Models and Algebraic Specifications

There are several reasons to specify UML models in a formal way The most important are to avoid inconsistencies and ambiguities and to do verification and forecasting of system properties. In this paper we propose a systematic approach to transform UML static models into algebraic specifications. We define the GSBL algebraic language to cope with concepts of UML. Firstly, we give a formal description for UML static models using GSBL. Then, we describe how to translate UML constructs to GSBL constructs. In particular, we show how to transform UML relations into GSBL. We propose a system of transformation rules to translate OCL constraints to GSBL.
