The Eclipse Modeling Framework (EMF) provides modeling and code generation facilities for Java applications based on structured data models. Henshin is a new language and associated tool set for in-place transformations of EMF models. The Henshin transformation language uses pattern-based rules on the lowest level, which can be structured into nested(More)
Model transformation is one of the key activities in model-driven software development. An increasingly popular technology to define modeling languages is provided by the Eclipse Modeling Framework (EMF). Several EMF model transformation approaches have been developed, focusing on different transformation aspects. To validate model transformations wrt.(More)
In this paper, we focus on the Conference Scheduling System, a case study at the Tool Contest of Graph-Based Tools (GraBaTs) 2008. We took part in the contest with our graph transformation tool AGG and the Eclipse-based EMF model transformation tool EMF Tiger. We present the features of both tools and evaluate their abilities to model the Conference(More)
The Eclipse Modeling Framework (EMF) provides a modeling and code generation framework for Eclipse applications based on structured data models. Although EMF provides basic operations for modifying EMF based models, a framework for graphical definition of rule-based modification of EMF models is still missing. In this paper we present a framework for(More)
The Eclipse Modeling Framework (EMF) provides a modeling and code generation framework for Eclipse applications based on structured data models. Within model driven software development based on EMF, refactoring of EMF models become a key activity. In this paper, we present an approach to define EMF model refactoring methods as transformation rules being(More)
In this paper, we consider a large variety of solutions for the generation of Sierpinski triangles, one of the case studies for the AGTIVE graph transformation tool contest [15]. A Sierpinski triangle shows a well-known fractal structure. This case study is mostly a performance benchmark, involving the construction of all triangles up to a certain number of(More)
Model-based development has an increasing importance in modern software engineering and other domains. Visual models such as Petri nets and UML diagrams proved to be an adequate way to illustrate many structural and behavioral system properties. However, while tooling for textual modeling is pretty mature now, visual tool builders are faced with a much(More)
This paper describes a model transformation from the Business Process Modeling Notation (BPMN) to the Business Process Execution Language for Web Services (BPEL4WS, or BPEL for short). We give the meta-models for both source and target language as EMF models and define EMF model transformation rules using our recently developed tool EMF Tiger, an Eclipse(More)
Visual modeling languages for discrete behavior modeling allow the modeler to describe how systems develop over time during system runs. Models of these languages are the basis for simulation with the purpose to validate the model with respect to its requirements. Graph transformation systems have shown to be suitable for the definition of various kinds of(More)
