In recent years, medical professionals are witnessing an explosive growth in data collected by various organizations and institutions. At the same time, the ongoing developments of networking technologies provide doctor with the capability to access these data across the boundaries of interconnected computers. In this paper we present a medical data(More)
The main objective of this paper is to present a flexible annotation management framework for a multimedia database system, applied to meeting recordings. Presented research and development activities are carried out within the scope of the IM2 project in which annotations play an important role in describing raw data from various points of view and in(More)
Caching is crucial to improve performances in many computing systems. It is context dependent, thus many types of cache exist. As a consequence, when a cache is required, it is usually built from scratch. Such a solution is time (and money) consuming, in particular in data grid context where several caches may be required. This paper proposes ACS (Adaptable(More)
Caching is crucial to improve performances in many computing systems. This work proposes a caching approach for improving query evaluation. The proposed solution follows a semantic oriented approach and combines query and object caching. Separating query and objects provides high flexibility, by making possible to use several cooperations between caches and(More)
This paper presents the MediaGrid project whose goal is the definition of a mediation framework for transparent access to largely distributed sources. Frameworks are reusable pieces of design being expressed as a set of interfaces and components together with the description of their collaboration. Research topics addressed by the MediaGrid project include(More)
Les caches sont traditionnellement utilisés pour optimiser les performances et sont souvent intimement liés aux applications ce qui les rend peu réutilisables et augmentent donc leur coût de conception. Nous proposons Adaptable Cache Service (ACS) un canevas logiciel pour la création de caches adaptables. Nous l’avons validé dans un intergiciel de données(More)
