Abstract
Document warehouses allow the storage of selected and filtered heterogeneous documents, as well as their exploitation through multidimensional analyses techniques. However, the content of documents is dynamic and changes across time. In practice, decisional analysts may be interested with various versions of documents. Thus, the document warehouse should store and manage these versions. This paper presents an extended generic model for document warehouses allowing the management of the multiversion documents. In addition, it interests with multidimensional analysis on documents versions.
