Metadata for multimedia documents

Abstract: In this article metadata for mulimedia documents are classified in conformity with their nature, and the different kinds of metadata are brought into relation with the different purposes intended. We describe how metadata may be organized in accordance with the ISO standards SGML, which facilitates the handling of structured documents, and DFR, which supports the storage of collections of documents. Finally, we outline the impact of our observations on future developments.

Using metadata for the intelligent browsing of structured media objects

Abstract: Interacting with a multimedia information system is different from interacting with a standard text-based information system. In this paper, we present the design of a system called Content-Based Hypermedia (CBH), which allows a user to utilize metadata to intelligently browse through a collection of media objects. We describe the approach we use to model data in order to make it browsable, explore our approach to browsing, which we call metadata mediated browsing, indicate how metadata is used in the concept of similarity, present the architecture of our system, and discuss indexing techniques for similarity browsing using content-based metadata and approaches to clustering which generate higher-level metadata to help the user browse more effectively.

Metadata Systems: Integrative Information Technologies

Abstract: Metadata systems are concerned with the management of data which describes other data (datasets, catalogues or actual database management systems) and are presently the subject of intensive research. Metadata systems can be used to store richly detailed forms of information, peform seamless wide-randing searches of information distributed across networks, and to integrate information stored in disparate repositories. Here we describe a model design and the methods of implementation derived from the experience of the Leicester University Metadata Project. Our approach utilises the incorporation of semantic metadata in addition to resource metadata, resulting in a generally more powerful system than existing global directory services. A feature of the class of design presented here is flexibility of implementation, with the ability to provide a coherent metadata system functioning above heterogeneous autonomous distributed databases
