The provisioning of multimedia services with guaranteed Quality-of-Service (QoS) is currently an important research issue in computer engineering, especially in the networking and information management areas. In this paper, we concentrate on the QoS-based provisioning of discovery and delivery services of multimedia resources in the educational application domain. We present a generic model for QoS-aware information management systems, able to support guarantee of the QoS in search and delivery of information objects over a network infrastructure (such as the Internet or an inter-organizations network). The model identifies actors and components involved, and their role. The metadata models we analyse are specialized for the education domain. For this application domain, we also propose QoS extensions to standard metadata models for profiling users, information services and resources, capable of supporting learning resources discovery and personalized delivery with QoS guarantee.

Abstract

The provisioning of multimedia services with guaranteed Quality-of-Service (QoS) is currently an important research issue in computer engineering, especially in the networking and information management areas. In this paper, we concentrate on the QoS-based provisioning of discovery and delivery services of multimedia resources in the educational application domain. We present a generic model for QoS-aware information management systems, able to support guarantee of the QoS in search and delivery of information objects over a network infrastructure (such as the Internet or an inter-organizations network). The model identifies actors and components involved, and their role. The metadata models we analyse are specialized for the education domain. For this application domain, we also propose QoS extensions to standard metadata models for profiling users, information services and resources, capable of supporting learning resources discovery and personalized delivery with QoS guarantee.
