Analyzing Robustness of UML State Machines

UML State Machines constitute an integral part of software behavior specification within the Unified Modeling Language (UML). The development of realistic software applications often results in complex and distributed models. Hence, potential errors can be ...

An OCL Semantics Specified with QVT

Slavisa Markovic

Metamodeling became in the last decade a widely accepted tool to describe the (abstract) syntax of modeling languages in a concise, but yet precise way. For the description of the language's semantics, the situation is less satisfactory and formal semantic ...

SeamCAD: Object-Oriented Modeling Tool for Hierarchical Systems in Enterprise Architecture

Alain Wegmann, Lam Son Lê

Enterprise Architecture (EA) requires modeling enterprises across multiple levels (from markets down to IT systems). Providing tool support for such models is a challenge (e.g. model containment hierarchy, navigation difficulties, problems to relate elemen ...

RoclET – A Tool for Wrestling with OCL Specifications

Slavisa Markovic, Cédric Jeanneret, Leander Eyer

In this paper, we describe the architecture and the functionality of our own OCL tool called RoclET. Besides standard features of OCL tools such as editing of class and object diagrams and parsing of OCL assertions (invariants, pre-/post-conditions), our t ...

RoclET– Refactoring OCL Expressions by Transformations

Slavisa Markovic, Cédric Jeanneret, Leander Eyer

The role of UML models in software development has changed considerably over the last years. While UML was used in its early days mostly as a notation for sketching ideas, developers more and more recognize now the value of a UML model as a formal document ...

Implementation of a Modeling Tool Using Alloy as Meta-Modeling Language and CrocoPat as Validation Tool

Alain Wegmann, Lam Son Lê, Dirk Thilo Beyer, Lotfi Hussami

The context of our work is a project that focuses on methods and tools for modeling enterprise architectures. An enterprise architecture model represents the structure of an enterprise across multiple levels, from the markets in which it operates down to t ...
