Although originally designed as an extension for the Unifi ed Modeling Language (UML), today, the Object Constraint Language (OCL) has been broadly adopted in the context of both UML and other modeling and domain-specifi c languages. However, appropriate tooling, supporting modelers and software developers on using OCL is still scarce and lacks important features such as debugging support. As OCL constraints are likely to become rather complex for real world examples, it is hard to comprehend the in uence of single OCL expressions and subexpressions on the result of a completely evaluated OCL constraint in the context of speci fic constrained objects. Therefore, debugging is of topmost importance for both constraint comprehension and maintenance. Thus, the major task of this work is to develop a graphical debugger integrated into Dresden OCL and the Eclipse Integrated Development Environment (IDE) to fill this gap.:1 Introduction
