Spoofax at Oracle: Domain-Specific Language Engineering for Large-Scale Graph Analytics

For the last decade, teams at Oracle relied on the Spoofax language workbench to develop a family of domain-specific languages for graph analytics in research projects and in product development. In this paper, we analyze the requirements for integrating language processors into large-scale graph analytics toolkits and for the development of these language processors as part of a larger product development process. We discuss how Spoofax helps to meet these requirements and point out the need for future improvements

GMF: A Model Migration Case for the Transformation Tool Contest

Using a real-life evolution taken from the Graphical Modeling Framework, we invite submissions to explore ways in which model transformation and migration tools can be used to migrate models in response to metamodel adaptation.Comment: In Proceedings TTC 2011, arXiv:1111.440

Metamodel adaptation and model co-adaptation

Abstract. Like other software artefacts, metamodels evolve over time. We propose a transformational approach to assist metamodel evolution by stepwise adaptation. In the first part of the paper, we adopt ideas from grammar engineering to define several semantics- and instancepreservation properties in terms of metamodel relations. This part is not restricted to any metamodel formalism. In the second part, we present a library of QVT Relations for the stepwise adaptation of MOF compliant metamodels. Transformations from this library separate preservation properties. We distinguish three kinds of adaptation according to these properties; namely refactoring, construction, and destruction. Coadaptation of models is discussed with respect to instance-preservation. In most cases, co-adaptation is achieved automatically. Finally, we point out applications in the areas of metamodel design, implementation, refinement, maintenance, and recovery.

Transformation of SDF syntax definitions in the ASF+SDF Meta-Environment

AbstractWe describe FST—a Framework for SDF Transformation. FST supports the adaptation (in a broad sense) of grammars based on the syntax definition formalism SDF. We further describe the prototype implementation of FST in the ASF+SDF Meta-Environment. Grammar transformations form an important concept of grammar reengineering, implementation, recovery and others. Tool support for grammar transformations is essential to automate the corresponding processes

Towards Agile Language Engineering

Language engineering is software engineering concerned with computer languages. Agile language engineering is the result of adapting agile principles to language engineering. An agile language engineering process is geared to ever changing requirements and fosters higher language quality, software quality, and developer productivity. It provides short iteration cycles, intensive user integration, control over frequent changes, and continuous delivery of valuable language tools. In this paper, we point out technological premises for agile language engineering; and we sketch how they are met by well-known as well as upcoming techniques and tools from language engineering
