    Ontology-enabled documentation of service-oriented architectures with ontobrowse semantic wiki
    (PRIMIUM - Process Innovation for Enterprise Software, 2009) Happel, Hans-Jörg; Seedorf, Stefan; Schader, Martin
    Documenting and maintaining an enterprise-wide service-oriented architecture (SOA) causes a substantial management effort, which should be addressed by intelligent, scalable solutions. A particular challenge is that business experts, developers, and software architects take different perspectives on a SOA, each favoring various description formats and sources, which leads towards a scattering of architectural information. Ontobrowse Semantic Wiki specifically addresses these issues by providing an ontology-based integration and documentation platform for architectural information. In this paper, we identify key issues arising from documentation and maintenance of a SOA by introducing the case of an insurance company. We give a detailed description of the Ontobrowse approach and its implementation, and explain how ontologies, artifact mappings, and architectural rules are created to support the Enterprise SOA case.

    A pragmatic approach to traceability in model-driven development
    (PRIMIUM - Process Innovation for Enterprise Software, 2009) Aleksy, Markus; Hildenbrand, Tobias; Obergfell, Claudia; Schader, Martin; Schwind, Michael
    A common problem in model-driven software development (MDSD) processes is the tracing of requirements across different phases of the software development life cycle and multiple levels of abstraction down to the code level. Because debugging at the model level is not feasible yet, unwanted or unexpected behavior of the executable system needs to be analyzed at the code level at run-time and in a feedback loop must be traced back to and handled at the model level. Thus, traceability is a very important success factor and quality criterion in software engineering and maintenance and especially when developing high-quality model-driven infrastructures. In this paper, we present the conceptual design and prototypical implementation of a lightweight traceability approach which supports tracing requirements across different models and levels of abstraction. While providing support for representing different types of traceability links between design models and implementation details, our approach can easily be integrated into existing MDSD projects without increasing their complexity.

    XML-Schema
    (Informatik-Spektrum: Vol. 25, No. 5, 2002) Hansch, Matthias; Kuhlins, Stefan; Schader, Martin
    XML hat sich als Sprache zur Definition von Dokumenten für den universellen Datenaustausch etabliert. XML-Schema ermöglicht ausgefeilte Definitionen für XML-Dokumente und hat beste Chancen, die bisher eingesetzte DTD abzulösen. Neben einer allgemeinen Einführung geht dieser Beitrag auch auf verfügbare Produkte und neue Möglichkeiten der objektorientierten Softwareentwicklung mit XML-Schema ein.
