....most commonly found in the software engineering research community are languages for modeling and or specifying some aspect of software or software process. Popular approaches include variations on statecharts, Petri nets, control flow diagrams, data flow diagrams, and hybrids among these [16, 20, 39, 50, 52, 54]. Many such languages are for specification only, and are not executable. Of those that are executable, some do support reacting to high level or domain oriented events and exceptions that can arise in the domain being modeled but, due to their high level focus, they provide little support for ....

....Hypermedia Design Method) 13] They utilise entity relationship diagrams, OMT or their own notation and techniques. Recently, some new approaches propose UML extensions for the hypermedia domain, for instance the development process of Conallen [4] the extension for multimedia applications in [12] and the UML extension of [1] The first approach is based on the Rational Unified Process (RUP) 9] and focuses particularly on the architecture of Web applications. The second one extends UML sequence diagrams to model multimedia processes. The third one provides modeling elements for the ....

.... Web hypermedia engineering represents an active research area, as also proved by the growing interest of journals and symposia for this topic [32, 29] In particular, in the last years several models and methodologies have been proposed for supporting the development of hypermedia applications [11, 14, 17, 18, 22, 27]. The main goal of such models is to help designers to reason in a structured way on aspects that are specific of hypermedia, such as links, structure, navigation, etc. Moreover, they should enhance the communication among the heterogeneous members of a hypermedia project, such as programmers, ....

....languages have been developed for software engineering. The Unified Modeling Language (UML) is the synthesis of many of such notations and it is considered a standard for the industrial development software. It is a modeling language, not a methodology, for object oriented design and analysis. In [11] UML has been extended to support the temporal synchronization of multimedia objects and to describe the spatial presentation, while in [16] UML has been extended on the base of OOHDM methodology, described in the following. Navigational modeling features have been added to UML, such as a new ....

....of standard UML. In this paper, we will demonstrate its suitability to specify the semantics of language extensions. As a case study, we present a specification of UML sequence diagrams and introduce a small extension for the modeling of multimedia applications (de rived from the OMMMA approach [21]) In comparison to existing approaches towards the formalization of UML collaborations sequence diagrams (e.g. 13, 18] dynamic meta modeling employs UML notation to present the (dynamic) semantics of behavioral diagrams. This approach has already been used to define the abstract syntax of the ....

....diagrams, in this and the following section we will present an extension for the modeling of multimedia presentation scenes. For this purpose, we consider sequence diagrams as they have been introduced for the language OMMMA L (Object oriented Modeling of MultiMedia Applications The Language; [21]) OMMMA L has been proposed as an extension of UML for the specification of interactive multimedia presentations. On an analysis level, an OMMMA model basically consists of = a class diagram containing application classes that may be related to media classes originating from a predefined media ....

....To overcome these shortcomings, we build on and extend the Unified Modeling Language (UML; 12] for the specific requirements of application modeling in the multimedia domain. UML allows to model diverse system aspects by a family of diagram types based on the paradigm of object orientation. In [13] we gave an overview of the OMMMA (Object oriented Modeling of MultiMedia Applications) approach and modeling language that constitutes the starting point for the more detailed presentation of integrated behavior modeling herein. We restrict the presentation to an analysis level of modeling, not ....

....capabilities. The contribution of this work to the field of applying visual modeling to multimedia software engineering is threefold: First, we present an integrated modeling language (method) for the specification of multiple aspects of multimedia applications. This approach was outlined in [13], but herein we clarify the details of behavior specification and the integration of interactive and timed procedural behavior. Second, the presented modeling approach does not invent a new language, but extends the standard objectoriented modeling language UML deploying UML s builtin extension ....

....give an overview of the diagram types of OMMMA L followed by a description of their combination. A more detailed description of OMMMA L, accompanied by a sample application illustrating the use of the different diagram types and language features to model a multimedia encyclopedia, can be found in [19]. 3.1 Class Diagram Class diagrams are the core of an object oriented application model and are used to describe the static part of the model aspect of the MV CMM model. Essentially, they consist of class and association definitions which describe the structure of objects and their possible ....

....i.e. the dynamic part of the model aspect of the MV CMM model. But in order to supply appropriate language abstractions to model specific characteristics of a multimedia application that are frequently needed, standard UML sequence diagrams have been extended by a series of features (see [19]) e.g. refinement of the time axis by time stamps and intervals, sequence diagram parameterization, activation and deactivation delays, simultaneous activation clustering as well as sequential activation composition, and timedependent media filters superimposed on activations. An example of an ....
