Abstract. Quality is often defined as fitness for purpose which is the key property to determine when evaluating quality. This paper presents some general requirements for evaluating quality frameworks. It also discusses characteristics of MDE that are important when building a quality framework, such as its use of models in several stages of development and maintenance, and its multi-abstraction level approach that requires consistency and traceability. MDE should strive for engineering of quality into software. As a step in extending quality frameworks for this purpose, we discuss integrating quality evaluation with quality engineering using MDE approaches. Applying it on transformations, we discuss both the transformability of models and the quality of transformations themselves. While completeness and precision of models are quality criteria for transformability of them, transformations should monitor and preserve model quality, be reusable, simple and efficient. We further discuss quality means and evaluation methods and propose future work. Keywords: Model-driven engineering, quality, transformation, metrics 1

Abstract: The Unified Enterprise Modelling Language (UEML) aims to support integrated use of enterprise and IS models expressed in a variety of languages. The achieve this aim, UEML provides a hub through which different languages can be connected, thereby paving the way for connecting the models expressed in those languages. UEML offers a structured approach to describing enterprise and IS modelling constructs, a common ontology to interrelate construct descriptions at the semantic level, a correspondence analysis approach to estimate semantic construct similarity, a quality framework to aid selection of languages, a meta-meta model to organise the UEML and a set of tools to aid its use. This paper presents an overview of UEML and points to paths for further work. 1.

Abstract. The paper presents a questionnaire to assess Domain Specific Languages based on a multi-dimensional framework for characterizing languages. An issue is whether and how to distinguish between characteristics of domain-specific and general purpose languages. We discuss how to emphasize dimensions that are particularly important for domain-specific languages such as being formal, yet transparent as well as integrable with other languages. We consider hazards and potentials of the approach.

Abstract. Goal modelling is emerging as a central requirements engineering (RE) technique. Unfortunately, current goal-oriented languages are not interoperable with one another or with modelling languages that address other modelling perspectives. This is a problem because the emerging generation of modeldriven information systems are likely to depend on coordinated use of several modelling languages to represent different perspectives on the enterprise and its proposed information system. The paper applies a structured approach to describe a well-known goal-oriented language, KAOS, by mapping it onto a philosophically grounded ontology. The structured approach facilitates language interoperability because, when other languages are described using the same approach, they become mapped onto the same ontology. The approach thereby provides an intermediate language for comparison, consistency checking, update reflection, view synchronisation and, eventually, model-to-model translation both between goal-oriented languages and between different languages. 1

Abstract. In keeping with the proliferation of free software development initiatives and the increased interest in the business process management domain, many open source workflow and business process management systems have appeared during the last few years and are now under active development. This upsurge gives rise to two important questions: What are the capabilities of these systems? and How do they compare to each other and to their closed source counterparts? In other words: What is the state-of-the-art in the area?. To gain an insight into these questions, we have conducted an in-depth analysis of three of the major open source workflow management systems – jBPM, OpenWFE and Enhydra Shark, the results of which are reported here. This analysis is based on the workflow patterns framework and provides a continuation of the series of evaluations performed using the same framework on closed source systems, business process modelling languages, and web-service composition standards. The results from evaluations of the three open source systems are compared with each other and also with the results from evaluations of three representative closed source systems: Staffware, WebSphere MQ and Oracle BPEL PM. The overall conclusion is that open source systems are targeted more toward developers rather than business analysts. They generally provide less support for the patterns than closed source systems, particularly with respect to the resource perspective, i.e. the various ways in which work is distributed amongst business users and managed through to completion.

We address three main problems regarding the use of the traditional dataflow language (TDL) for modelling large and dynamic networks: • The problem of scalability. The concepts and notations of TDL do not scale well. Thus TDL specifications may get large (space consuming) and chaotic. • The problem of generality. TDL does not have the expressibility for specifying networks consisting of n (a general number) components. We distinguish between five different network topologies consisting n components that can not be specified in TDL. For point-to-point networks these are the star, ring and tree topologies, for multipoint networks the ring and the bus topologies. • The problem of expressing dynamic reconfiguration. TDL is not well suited for the specification of dynamic networks. We distinguish between three kinds of dynamic networks: object-oriented networks, ad hoc networks, and mobile code networks. Based on an examination of three state-of-the-art modelling languages (FOCUS, SDL-2000 and UML 2.0), we propose a language, MEADOW (Mod-Elling lAnguage for DataflOW) that essentially is an extension of TDL. Our hypothesis is that MEADOW successfully solves the problems mentioned above, and we argument by small examples and case studies. iii iv Foreword This thesis is submitted for the fulfilment of the Cand.
