  abstract     = {{An analysis of how visual modeling of structure and dynamic behavior of a multimedia application differs from modeling conventional software yields that aspects of the graphical user interface and time-dynamic behavior ought to be integral parts of a coherent multimedia application model. In this sense, we extend the model-view-controller paradigm towards multimedia.As a result, we present OMMMA-L, a visual Language for the Object-Oriented Modeling of MultiMedia Applications that is based on the Unified Modeling Language (UML). The structural and behavioral diagram types of UML have been analyzed and are adapted and extended according to multimedia application characteristics.A presentation diagram is introduced and integrated to adequately describe the visual presentation. In addition to explaining the different diagram types, we also give pragmatic guidelines on how to deploy and combine the various diagrams.}},

  abstract     = {{Der Entwicklungsprozeß von Multimediaanwendungen sollte ebenso wie der herkömmlicher Softwaresysteme eine Analyse und einen Entwurf beinhalten. In dieser Arbeit diskutieren wir, inwiefern die Modellierung der Struktur und des dynamischen Verhaltens einer Multimediaanwendung über die Modellierung herkömmlicher Software hinausgeht. Wir zeigen, daß Aspekte der Benutzungsschnittstelle und das Zeitverhalten integraler Bestandteil der Modellierung sein sollten. Als Ergebnis stellen wir die objektorientierte Modellierungssprache OMMMA-L vor, die auf der Unified Modeling Language (UML) aufbaut. Die Struktur- und Verhaltensdiagramme von UML wurden analysiert und gemäß der Charakteristika von Multimedia adaptiert bzw. erweitert. Im Klassendiagramm werden die Medientypen und die logische Struktur der Anwendung modelliert. Als Verhaltensdiagramme werden spezialisierte Sequenz- und Zustandsdiagramme eingesetzt. Mit dem Layoutdiagramm wird ein neuer Diagrammtyp hinzugefügt, der die integrierte und anschauliche Beschreibung der visuellen Darstellung und interaktiver Benutzereingaben einer Multimediaanwendung erlaubt. Neben der Vorstellung der einzelnen Diagrammtypen geben wir ein aus dem Metamodell zu UML abgeleitetes OMMMA-L-Metamodell an, in dem das Zusammenspiel der Modellelemente aus den verschiedenen Diagrammen spezifiziert wird.}},

  abstract     = {{In this paper, dynamic meta modeling is proposed as a new approach to the operational semantics of behavioral UML diagrams. The dynamic meta model extends the well-known static meta model by a specification of the system’s dynamics by means of collaboration diagrams. In this way, it is possible to define the behavior of UML diagrams within UML. The conceptual idea is inherited from Plotkin’s structured operational semantics (SOS) paradigm, a style of semantics specification for concurrent programming languages and process calculi: Collaboration diagrams are used as deduction rules to specify a goal-oriented interpreter for the language. The approach is exemplified using a fragment of UML statechart and object diagrams. Formally, collaboration diagrams are interpreted as graph transformation rules. In this way, dynamic UML semantics can be both mathematically rigorous so as to enable formal specifications and proofs and, due to the use of UML notation, understandable without prior knowledge of heavy mathematic machinery. Thus, it can be used as a reference by tool developers, teachers, and advanced users.}},

  abstract     = {{Several software architecture paradigms have been proposed for the development of interactive software systems and applications. Their common idea is the separation of user interface components from application logic. Normally, they are deployed as design patterns or basic frameworks of interactive systems. Deploying these architecture paradigms for multimedia systems or embedded real-time systems, first requires an appropriate adaption to the specific aspects of these application areas. We will compare within this position paper two well-known architecture paradigms and motivate an advanced architecture paradigm applicable to real-time, embedded multimedia systems. In addition, we will discuss that the architecture paradigm should be reflected within the structure of a modeling language.}},
