....[11, 17, 21] of modeling multimedia systems. For example, the object oriented approach allows to model application specific data types and classes including associated operations. This is also the reason why most approaches for multimedia database systems follow object oriented principles (e.g. [1, 5, 9, 13, 15, 17, 27]) However, the conventional object oriented approach still lacks some features such as supporting time dependent data, content based query and retrieval techniques [16] etc. In particular, it does not support the concept of roles. In this paper, we propose the use of roles and views in a dynamic ....

....further specify how information is presented and captured. MIM support images, voice and analog video. The problem of version control has also been investigated. Among multimedia databases, most of the work done up to now favors the objectoriented approach and suggests the use of an OODBMS, e.g. [1, 5, 9, 10, 13, 15, 17, 27]. With minor divergences, the constructs which should be supported by the multimedia data model, such as those in [11, 17, 27] are widely accepted. As storage requirements of multimedia data are large, techniques to minimize storage space on the physical level (e.g. compression techniques) and ....

....may be of arbitrary types, is important. This may cause problems when processing and presenting documents. A straightforward solution for a distinct set of DTDs is to leave the interpretation and presentation to the application. More sophisticated solutions are beyond the scope of this article [4]. Metadata in SGML documents may be organized as follows: ffl The DTD may contain certain element types for the metadata. An obvious example is an element type keywordList in a DTD scientificPublication. If the metadata are organized in that way, in essence they cannot be distinguished from the ....

....the clients as it keeps them independent from the specific format in which the multimedia document is stored. The VODAK database management system provides powerful modeling capabilities that are sufficient to handle structured documents. This has been proven in the case of SGML documents [BKN95, BA94, ABH94, BAH94] Based on the VODAK modelling language (VML) DIM95, KAN94] a suitable representation for any structured document model can be found even if it contains multimedia components. As a consequence, we can offer several models for multimedia documents at the server, e.g. for HyTime ....

....requirements. The general technique of tailoring VML is illustrated in [KAN94] following the application requirements for modeling hypermedia documents as they are used in the framework of, for example, collaborative authoring environments. Other examples for tailoring VML can be found in [AKF94, BA94, BAH94, HGPK94] The same techniques are employed to describe the mappings of external schemas to ex Sec. 1.2. Database Integration Environment 11 port schemas specified in VML [KFA94] Specific requirements and solutions for integrating multimedia data in VODAK are described in [AK93, ....

....concepts to handle multimedia documents in detail. The VODAK database management system provides powerful modeling capabilities that are sufficient to build up complex document structures, as they are necessary to represent structured documents. This has been proven in the case of SGML documents [5, 3, 1, 4]. Based on the VODAK modeling language (VML) 10, 18] a suitable representation for any structured document model can be found, even if it includes multimedia components. As a consequence, we can offer several models for multimedia documents at the server, e.g. for HyTime [23] MHEG [15] object ....

These include the quite natural and general application domain of multimedia document management and processing (e.g. [3, 33]) multimedia mail systems including voice mail systems (e.g. 35, 34] teleconferencing applications, and kiosk information or point of sale systems. 4.1 Product Documentation for a Systems Engineering Environment At the Technical University of Darmstadt the research group MUSE 2 was formed ....

....place in the AMOS (Active Media Object Stores) department. The objective is the development of the concepts needed for a true MM DBMS and their integration within the existing object oriented database management system VODAK. Main topics of research are modeling of multimedia information [AK94, BA94, BR94, KNS90] and support for time dependent data [RM93, RLM 93] Prototypes were developed and used in applications in telecommunication environments [R 94, TR94] The AMOS developments serve as an illustrating example of the features and the architecture of a MM DBMS in this article. ....

....[VAB95] Combining structural queries with IRS queries leads to non trivial questions with regard to retrieval semantics and query processing. Further, the VODAK DBMS supports the management of user definable typed document structures according to SGML and the hypertext features of HyTime [ABH94, BA94, ISO86, ISO92] In the sequel, we give some examples of possible queries in this system: Select the authors of all chapters whose introduction is about multimedia databases Select the titles of all sections on the information highway Naturally, such queries require that the ....

....desktop and database environment. Storage and manipulation of hyperstructures and the documents contained in the hypernodes are modeled at the database level[KAN93] In addition to the management of conventional data, the underlying database management system VODAK[GMD95, RL94, AK94, KNS90, BA94] offers mechanisms for the storage, manipulation and presentation of multimedia data. Therefore, the system allows an extended notion of documents including text, images, audio, video and data produced from the tools of the MuSE environment. The object oriented model of the documents contains ....
