7th International Workshop on Graph Based Tools (GraBaTs 2012): Preface

The 7th International Workshop on Graph Based Tools is the continuation of the GraBaTs series of workshops which provides a forum for researchers and practitioners interested in the development and application of graph-based tools. The purpose of this workshop is to survey the state of the art of graph-based tools, bring together developers of graph-based tools in different application fields and to encourage new tool development cooperations. GraBaTs 2012 is the 7th edition in a line of workshops which started 10 years ago at ICGT'02

ModGraph meets Xcore: Combining Rule-Based and Procedural Behavioral Modeling for EMF

Model-driven software engineering aims at increasing productivity bydeveloping high-level executable models. The Eclipse Modeling Framework (EMF)significantly contributes toward this goal. Unfortunately, EMF supports only structural models based on the Ecore metamodel. Recently, Xcore has been developed to extend EMF with behavioral modeling. To this end, Xcore provides a single textual language for both structural and behavioral modeling. While Xcore follows a procedural approach to behavioral modeling, ModGraph is an EMF-based tool based on a rule-based paradigm (graph transformation rules, which allow to specify behavior in a declarative way). The combination of EMF, Xcore, and ModGraph results in an environment for model-driven software engineering which provides full-fledged support for both structural and behavioral modeling. Altogether, we obtain an environment in which software engineers are concerned only with models rather than with programs

Integrierte Softwaremessung durch Verankerung der Softwaremaße an Elementen des Vorgehensmodells

Wird Softwaremessung mit dem Ziel der Prozessverbesserung angewendet, so sollte die Erfassung der Messwerte in geeigneter Weise standardisiert erfolgen, um verschiedene Softwareentwicklungsprojekte vergleichen zu können. Dieser Beitrag stellt einen Ansatz vor, die Softwaremaße an den Elementen des dem Entwicklungsprozess zugrunde liegenden Vorgehensmodells zu verankern. Neu dabei ist, dass wir nicht nur Projektmeilensteine, sondern beliebige im Vorgehensmodell definierte Aktivitäten oder Produkte als Anknüpfungspunkte für die Softwaremaße verwenden. Dadurch ist es möglich, die relevanten Softwaremaße unabhängig von einem konkreten Projekt festzulegen. Über den Projektstrukturplan wird zur Laufzeit des Projekts die Verbindung von den Aktivitäten des Vorgehensmodells zu den tatsächlich zu messenden Entitäten hergestellt. Durch den Einsatz des Projektverwaltungstools Maven kann dann die Erfassung der Softwaremaße automatisiert durchgeführt werden

Triple Graph Grammars or Triple Graph Transformation Systems? A Case Study from Software Configuration Management

Abstract. Triple graph grammars have been used to specify consistency maintenance between inter-dependent and evolving models at a high level of abstraction. On a lower level, consistency maintenance may be specified by a triple graph transformation system, which takes care of all operational details required for executing consistency maintenance operations. This paper presents a case study from software configuration management in which we decided to hand-craft a triple graph transformation system rather than to generate it from a triple graph grammar. The case study demonstrates some limitations concerning the kinds of consistency maintenance problems which can be handled by triple graph grammars
