Zusammenfassung. Der Ansatz der modellgetriebenen Softwareentwicklung fokussiert Modelle als Spezifikation von Software und deren automatische Transformation bis hin zum Quellcode der gewünschten Zielplattform. Da eine durchgehende Werkzeugunterstützung unter Berücksichtigung aller Aspekte eines Softwaresystems bisher nicht möglich ist, muss der Mehrwert der modellgetriebenen Ansätze noch nachgewiesen werden. Die Durchgängigkeit ist dabei unter anderem auf Grund ungenügender oder fehlender Metamodelle zur Beschreibung einiger Aspekte eines Softwaresystems nicht gegeben. Der hier vorgestellte Ansatz greift den Aspekt der Benutzerinteraktion heraus und zeigt, wie durch die Erweiterung einer Modellierungssprache auf Metamodellebene eine werkzeugunterstützte, modellgetriebene Entwicklung plattformunabhängiger Benutzerschnittstellen ermöglicht wird. Eine Fallstudie demonstriert dabei die Machbarkeit und den Mehrwert dieses Ansatzes.Summary. The approach of model-driven software development focuses on models as specification of software and on transformations of those models to finally get the source code. The advantage of the model-driven approach still has to be proven because a continuous tool-supported transformation process from model to source code with regard to all aspects of a software system is not possible yet. The lack of continuity in tool-support is among other reasons based on inappropriate or missing metamodels for describing certain aspects of a software system. The presented approach concentrates on the aspect of user interaction and demonstrates, how an extension of a modeling language allows for a tool-supported, model-driven software development of graphical user interfaces for any kind of platform. A case study demonstrates the feasibility and benefit of this approach.

Abstract-The establishment of IT-supported processes within organizations requires the integration of existing distributed legacy applications. Therefore, Web services can be generated as wrappers to flexibly integrate existing distributed legacy applications using a standardized interface. Existing approaches mostly focus on the technical issues of the integration using Web services and do not support the developer during the description of an integration processes. Thus, in this paper we introduce a development approach that supports the developer in describing an integration process and finally allows a model-driven transformation of the prior defined integration process into Web service interfaces and XML schema definitions. Our approach is exemplified by a scenario at the Karlsruhe Institute of Technology (KIT) that implements a process to visualize the study progress of a student.

In today's continuously changing markets newly developed products often do not meet the demands and expectations of customers. Research on this problem identified a large gap between developer and user expectations. Approaches to bridge this gap are to provide the developers with better information on product usage and to create a fast feedback cycle that helps tackling usage problems. Therefore, the user interface of the product, the central point of human-computer interaction, has to be instrumented to collect accurate usage data which serves as basis for further improvement steps. This paper presents a novel engineering approach that combines model-driven user interface development and flexible instrumentation with run-time monitoring. In its application, it enables observation integration into products which provides comprehensive data about usage and thus allows for fast feedback cycles and consequently increased software quality. A casestudy demonstrates the applicability of this approach.
