Definitions and approaches to model quality in model-based software development - A review of literature

More attention is paid to the quality of models along with the growing importance of modelling in software development. We performed a systematic review of studies discussing model quality published since 2000 to identify what model quality means and how it can be improved. From forty studies covered in the review, six model quality goals were identified; i.e., correctness, completeness, consistency, comprehensibility, confinement and changeability. We further present six practices proposed for developing high-quality models together with examples of empirical evidence. The contributions of the article are identifying and classifying definitions of model quality and identifying gaps for future research.

Toward standardised model to text transformations

The objective of this work is to assess the qualities of the MOFScript language, which has recently been submitted to the OMG as a proposed model to text transformation language. This is done by identifying requirements for this type of language and evaluating the MOFScript language with regard to these. The language is presented along with a tool implementation and compared with the alternative languages submitted to the OMG Model to Text RFP.

Towards an Interoperability Framework for Model-Driven Development of Software Systems

This paper presents an interoperability framework for model-driven development of enterprise applications and software systems. The framework provides a foundation for how to apply MDD in software engineering disciplines in order to support the business interoperability needs of an enterprise. The framework introduces reference models for conceptual integration, technical integration and applicative integration of software systems.

Semaphore – a model-based semantic mapping framework

This paper presents a framework and a tool devised to aid in obtaining information interoperability between enterprise applications. The approach has its foundations in the principles of model-driven architecture (MDA) and architecture-driven modernisation (ADM). The key idea is that mappings between different information formats are defined at a platform-independent level, and that the mechanisms that actually perform the needed data conversion are generated based on the mappings according to the relevant platforms of the systems at hand.

Guest editorial to the theme issue on traceability in model-driven engineering

This issue of Software and Systems Modeling, and part of the issue that follows, are dedicated to the theme of traceability in model-driven engineering (MDE). Traceability is a fundamental concern in MDE processes, where models are related via application of different model management operations, such as model-to-model transformations, modelto-text transformations, model merging, model comparison, and many others. MDE emphasises on the application of automated model management operations, and substantial traceability information can be produced as a side-effect of applying these operations. In addition, in realistic MDE processes, traceability information can be produced by hand, through engineers manually relate MDE artefacts, or relate MDE artefacts with other artefacts (such as requirements documents). Overall, there are many challenges to traceability in MDE, ranging from managing large traceability models, to synchronizing models, and to keep traceability information consistentwhenmodels are beingmodified automatically and manually. This theme issue presents state-ofthe-art research on these and other challenges. Since 2005, the ECMDA-FA/ECMFA Workshop on Traceability has presented the leading research on traceability in MDE. After the 2008 workshop in Berlin, authors of accepted papers from the previous four workshops were invited to submit their latest results (perhaps derived from their workshop papers) to this theme issue. At the same time, an open call was issued, soliciting submissions from the

A flexible framework for development of component-based distributed systems

This paper describes a generic framework facilitating the specification and construction of component-based distributed systems. The framework integrates methods for specification of systems with tools supporting the construction of those systems. This is achieved by defining a reference architecture supported by a metamodel, a Component Modelling Language and tools for code-generation. The metamodel is an extension of the UML metamodel. The Component Modelling Language is a lexical description language based on CORBA IDL.
