Multimedia Database Systems — The Notions and the Issues

In this article, we give an overview of the usage of database systems in the emerging field of multimedia computing systems. We motivate that management of multimedia information requires support of temporal relationships, interactive operations, high data volume, and transport of multimedia data. The solutions achieved so far vary to which extend multimedia applications are supported. We suggest to use the notions of hybrid, structural, behavioral, and distributed multimedia systems to classify them. We emphasize the current issues in the area of multimedia database research. Multimedia data modeling, content-based retrieval, continuous storage management, and a distributed architecture are the constituents of multimedia database management systems. The developments achieved so far with the AMOS prototype currently under development at our institutes serve as an illustrating example of current efforts. Specifically, the design of a datatype for audio information, the modeling of meta information and of interactive multimedia presentations, the development of an object manager for continuous objects, and the integration of an information retrieval system in our system are described.

ODBASE 2006 international conference (ontologies, databases, and applications of semantics) PC co-chairs' message

Welcome to the Fifth International Conference on Ontologies, Databases, and Applications of Semantics (ODBASE 2006) This years ODBASE conference was held in Montpellier, France from October 29 to November 3, 2006. n nThe ODBASE conferences provide a forum for exchanging the latest research results on ontologies, data semantics, and other areas of computing related to the Semantic Web We encourage participation of both researchers and practitioners in order to facilitate exchange of ideas and results on semantic issues in Web information systems Towards this goal, we accepted both research and experience papers.
