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 by supplying different query management tools. Our proposition has been experimented in a grid data management middleware and seems promising as showed by the results reported in this paper.
