Metamodeling or profiling: a practical case in the web engineering domain

Model Driven Development (MDD) provides several choices for the definition of modeling languages. The definition of a complete metamodel and the customization of a given metamodel using profiles are common approaches. In our opinion neither of these approaches is better than the other, and the choice should depend on the characteristics of each project. This paper describes our experiences defining a graphical notation for the characterization of web navigational maps based on a MOF metamodel and a UML profile. The advantages and drawbacks of both approaches are examined, as well as the solution selected for our project.Presentado en el VIII Workshop Ingeniería de Software (WIS)Red de Universidades con Carreras en Informática (RedUNCI

Modernizing science&engineering software systems

As the demands for modernized legacy systems rise, so does the need for frameworks for information integration and tool interoperability. The Object Management Group (OMG) has adopted the Model Driven Architecture (MDA), which is an evolving conceptual architecture that aligns with this demand. MDA could help solve coupling problems of multidisciplinary character in science and engineering that consist of one or more applications, supported by one or more platforms. The objective of this paper is to describe rigorous techniques to control the evolution from science & engineering software legacy systems to MDA technologies. We propose a rigorous framework to reverse engineering code in the context of MDA. Considering that validation, verification and consistency are crucial activities in the modernization of systems that are critical to safety, security and economic profits, our approach emphasizes the integration of MDA with formal methods

Ontological Multilevel Modeling Language

This paper presents ontological multilevel modeling language O2ML, aimed at using with metadata driven information systems. The first part of this paper briefly surveys existing modeling languages and approaches, while the last part proposes a new language to combine their benefits

Experiences in teaching a graduate course on model-driven software development

Cataloged from PDF version of article.Model-driven software development (MDSD) aims to support the development and evolution of software intensive systems using the basic concepts of model, metamodel, and model transformation. In parallel with the ongoing academic research, MDSD is more and more applied in industrial practices. After being accepted both by a broad community of researchers and the industry, it is now being introduced in university courses. This article describes the experiences of three years of teaching of the graduate course Model-Driven Software Development at Bilkent University in Turkey. The lessons learned can be useful for peer educators who teach or aim to teach a similar course. © 2011 Copyright Taylor and Francis Group, LLC

Science & engineering software migration: moving from desktop to mobile applications

The proliferation of mobile devices over the last years provides opportunities and challenges for solving problems in Science & Engineering. Among other novel features, mobile devices contain global positioning sensors, wireless connectivity, built-in web browsers and photo/video/voice capabilities that allow providing highly localized, context aware applications. Mobile phones have become as powerful as any desktop computer in terms of applications they can run. However, the software development in mobile computing is still not as mature as it is for desktop computer and the whole potential of mobile devices is wasted. A current problem in the engineering community is the adaptation of desktop applications for mobile technologies. To take advantage of new platform technologies, existing software must evolve. A number of solutions have been proposed to deal with this problem such as redevelopment, which rewrites existing applications, or migration, which moves the existing system to a more flexible environment while retaining the original system data and functionality. A good solution should be to restore the value of the existing software, extracting knowledge and exploiting investment in order to migrate to new software that incorporates the new technologies. On the one hand, traditional reverse engineering techniques can help in the software migration to mobile applications. They are related to the process of analyzing available software with the objective of extracting information and providing high-level views on the underlying code. On the other hand, to achieve interoperability with multiple platforms the migration needs of technical frameworks for information integration and tool interoperability such as the initiative of the Object Management Group (OMG) called Model Driven Architecture (MDA). The outstanding ideas behind MDA are separating the specification of the system functionality from its implementation on specific platforms and managing the software evolution from abstract models to implementations increasing the degree of automation. The objective of this paper is to describe a reengineering process that allow moving existing desktop applications for solving engineering problems of multidisciplinary character to mobile platforms. Our research aims to simplify the creation of applications for mobile platforms by integrating traditional reverse engineering techniques, such static and dynamic analysis, with MDA. We validated our approach by using the open source application platform Eclipse, EMF (Eclipse Modeling Framework), EMP (Eclipse Modeling Project) and the Android platform
