Delta modeling is an approach for capturing variability resulting from different configurations and for deriving concrete software products of an SPL or SECO through transformation. Even though the general concepts of delta modeling are languageindependent, custom delta languages are required for all source languages, which are tedious to create and lack interoperability due to different implementation technologies. In this paper, we present a framework to automatically derive delta languages for textual or graphical languages given as EMOF-based meta models. We further illustrate how to automatically generate the syntax and large parts of the semantics of the derived delta language by inspecting the source language's meta model. We demonstrate our approach by applying our implementation DeltaEcore to four selected source languages. 2014-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/20957 Difference-based Conformance Checking for Ecore Metamodels Burger, Erik; Toshovski, Aleksandar Fill, Hans-Georg; Karagiannis, Dimitris; Reimer, Ulrich During modern model-driven development processes, generators and higherorder transformations are used to create metamodels with short life cycles. Since these metamodels often differ from each other only in small parts, instances as well as metamodels may be re-used if the difference between them does not lead to a violation of instance conformance. Existing co-evolution approaches describe this conformance based on change operators to a metamodel. Thus, they require that changes to the metamodels are carried out using special editors. To use this conformance for arbitrarily generated metamodels, we present a conformance validator for Ecore metamodels that is based on difference-based analysis. The validator has been implemented as a plug-in for the Eclipse framework. We demonstrate the completeness of our approach by covering state-of-the-art co-evolution change operators. 2014-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/20954 Towards a Modeling Method for Supporting the Management of Organizational Decision Processes Bock, Alexander; Kattenstroth, Heiko; Overbeek, Sietse Fill, Hans-Georg; Karagiannis, Dimitris; Reimer, Ulrich Today's business environments necessitate effective and well-informed organizational decision processes. To establish adequate environments for decision processes in organizations, methods are advisable that promote the coordination of these processes, facilitate the implementation and maintenance of supporting information systems, and foster accountability as well as traceability of organizational decisions. We investigate the potentials of an enterprise modelingbased approach for supporting the management of organizational decision processes and propose conceptualizations for modeling constructs as enhancements to existing enterprise modeling methods. 2014-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/20955 Echtzeitmetamodellierung im Web-Browser Derntl, Michael; Erdtmann, Stephan; Nicolaescu, Petru; Klamma, Ralf; Jarke, Matthias Fill, Hans-Georg; Karagiannis, Dimitris; Reimer, Ulrich Modellierung ist ein integraler Bestandteil von Schaffensprozessen in vielen Disziplinen. Der Modellierungsprozess wird durch vielfältige Tools unterstützt, von denen jedoch die wenigsten eine gemeinsame Modellierung durch mehrere Modellierer ermöglichen und die mittels offener Technologien und Protokolle realisiert sind. Um diese Lücke zu schließen, konzipieren wir in diesem Beitrag ein Framework für Echtzeitmetamodellierung, das als Widget-basierte Anwendung realisiert wird und ausschließlich auf quelloffenen Programmbibliotheken und breit implementierten Web-Technologien basiert. Der Beitrag berichtet über eine vorab durchgeführte Technologiestudie, bei der ein Echtzeitmodellierungstool für eine bestimmte Anwendung realisiert und erfolgreich evaluiert wurde. Das Metamodellierungsframework wurde durch Abstrahierung und Erweiterung der Technologiestudie auf Metamodellebene konzipiert und soll die Verbreitung von Echtzeitkollaborationsfunktionen in Web-Anwendungen vorantreiben. 2014-01-01T00:00:00Z
