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 optimi-ser 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 intergi-ciel de données(More)
This paper focuses on context-aware data management services in grids with the aim of constructing self-adaptive middleware. The contribution is twofold. First it proposes a framework to facilitate the development of context management services. The reason is that, even a context management service, is context specific. The creation of ad-hoc context(More)
