The traditional multidimensional models have a static structure where members of dimensions are computed in a unique way. However, data (particularly multimedia data) is often characterized by descriptors that can be obtained by various computation modes. We define these computation modes as "functional versions" of the descriptors. We propose a Functional Multiversion Multidimensional Model ("F2M model") by integrating the concept of "version of dimension". This concept defines dimensions with members computed according to various functional versions. In order to allow the user to choose the best representation of data, this new approach integrates a choice of computation modes of these members into the model. We implement a multimedia data warehouse in the medical field by integrating the multimedia data of a therapeutic study into a multidimensional model. We formally define a conceptual model and we present a prototype for this study.
