Motrusca : interactive model transformation use case repository

Modeling and model transformations tools are maturing and are being used in larger and more complex projects. The advantage of a modeling environment and its transformation tools cannot be easily exploited by non-expert users as many subtle intricacies determine the efficiency of transformation languages and their tools. We introduce transformation use case examples that highlight such language/tooling properties. These simple, non-trivial examples have been extracted from an experiment with transformations of Design Space Exploration models. These examples show some typical modeling patterns and we give some insight how to address the examples. We make a case for initiating an interactive, on-line repository for model transformation use cases. This repository is aimed to be example-centric and should facilitate the interaction between end-users and tooling developers, while providing a means for comparing the applicability, expressivity, and efficiency of transformation tools

Modelling the role of the design context in the design process: a domain-independent approach

Domain-independent models of the design process are an important means for facilitating interdisciplinary communication and for supporting multidisciplinary design. Many so-called domain-independent models are, however, not really domain independent. We state that, to be domain independent, the models must abstract from domain-specific aspects, be based on the study of several design disciplines, and be useful for many design disciplines and for multidisciplinary design teams. This paper describes a domain-independent descriptive design model that is developed by studying similarities and differences between design processes in a few design disciplines. The model is based on the general theory of state transitions. We modelled a design situation as a state at a certain moment and a design activity as a transition. We also explicitly modelled the role of the design context in design processes. In our empirical studies, we noticed the influence of the design context on the product being designed and the design process and the importance of communication between designers and stakeholders in the design context regularly during the design process. Making designers aware of the role of the design context can improve the quality of both the product being designed and the design process. The role of the design context is, however, often not explicitly taken into account in design models. We modelled the design context as part of the state at a certain moment and interaction with the design context as one of the activities performed by designers

AmbiDexter: Practical Ambiguity Detection

Ambiguity detection tools try to statically track down ambiguities in context-free grammars. Current ambiguity detection tools, however, either are too slow for large real- istic cases, or produce incomprehensible ambiguity reports. AmbiDexter is the ambiguity tool to have your cake and eat it too
