....The predefined temporal behavior represented in OMMMA L sequence diagrams resembles the specification of a presentation plan specifying the playout scheduling for the multimedia application. For instance, in the AMOS client server architecture, a prototypical multimedia database system (see [2]) it is computed by the multimedia database server for presenting the results of a query and executed by a database client running the application. If we regard a query as one possible user interaction, it can be mapped to a transition in the OMMMA L state diagram, where the entered state ....

.... The generic spatio temporal composition scheme for events, based on the EBNF notation, is defined as follows: op : e1 Rel e 2 Rel : temporal relation, spatial relation, sp temp dist) temporal relation : after before simultaneously spatial relation : R i j i, j : [1,13] spatio temp dist : spatio temporal distance 5. Sample Event Definition and Event Composition In this Section, we present an example that demonstrates the potential of our proposal. In the following application specific event definitions, only the appropriate attributes have values attached. ....

....based architecture manages events in the context of IMAPs persistently on the server and provides a multimedia database client that generates, evaluates, and processes the events produced in the context of the execution of an IMAP. We are based on the AMOS system for the implementation of events [1, 14]. With the implementation of the event concept we aim at extending the interactive features of the AMOS prototype considerably. Hereafter, we elaborate on the modifications and extensions of the AMOS system components in order to support IMAPs. The integrated approach of the AMOS system is to ....

....that an MM DBMS should provide presentation independence as it provides data independence. Then, application programs are relieved from specific data codings as well as time dependencies in presentations. We call the service supporting presentation independence at the client playout management [BKL96, TK96]. It offers synchronized presentation of user modeled compositions of discrete as well as continuous data. In addition, it supports user interaction to control the presentation (start, stop, 4 etc. provides for user initiated selection of presentation parts (e.g. branching) and allows for ....

.... retrieval of multimedia information within the DBMS [SK98] Another challenging issue in this context is to provide techniques for continuous media data delivery and presentation services integrated into a database system in order to achieve really multimedia capable database system support [BKL96,MKK95] Background for this work is the project Gallery of Cardiac Surgery (CardioOP) 1 which aims at the development of a network based and database driven multimedia information system for physicians, medical lecturers, students, and patients in the domain of cardiac surgery. The overall ....

....description of documents. With such a description it is possible to convert a document to other document formats like SMIL or MHEG 5. The conversion functionality can be implemented using server based routines, too. Finally, the architecture of a multimedia database system as proposed by [KA97,BKL96] calls for the integration of the presentation and playout of media content in the DBMS itself. As Cardio OP evolves, we will evaluate how server based routines can be used to contribute to this integration. The routines developed in our project so far can roughly be divided into three groups: ....

The AMOS project (Active Media Object Stores) at GMD IPSI currently develops a multimedia database management system (MMDBMS) which allows for the integrated management and presentation of multimedia data and multimedia applications [RNL95, BKL96, TK96] The AMOS prototype is based on a client server architecture.

It allows for the management of multimedia data and currently supports storage, retrieval, and execution of preorchestrated multimedia presentations [BKL96] however with limited interaction support. But since an IMAP may have extended repertoire of interactions, the new event concept proposed in this paper is implemented in this multimedia database environment to support the definition and execution of multimedia applications with highly ....

The Z Y X model has been implemented as a DataBlade module for the objectrelational database system Informix Dynamic Server Universal Data Option under Sun Solaris, following the architectural framework initially presented in (Klas and Aberer, 1997; Boll et al. 1996). Ongoing work includes the identification and realization of possible optimizations of the implementation of the DataBlade. The formal description served as the basis for the definition of an XML DTD for the Z Y X model 2 . This will enable access to content stored in the Cardio OP repository ....

We have developed a database schema that allows for the modeling and storage of multimedia documents by means of extended Object Composition Petri Nets [BKL96] This database schema includes methods that map a multimedia document into a presentation plan, i.e. an internal format that encodes all information relevant to the presentation of the document.

Additionally, we have developed a VML database schema that enables the modeling and storage of multimedia documents. To describe multimedia documents, we use presentation nets [BKL96] which add several features to Object Composition Petri Nets [LG90] Our database schema includes the mapping of a multimedia document into a presentation plan, i.e. an internal format that encodes all information relevant to the presentation of the document. Basically, a presentation plan ....
