Documents constitute a capitalization of knowledge within organizations’ Information Systems. Therefore, the management of the contents of these documents represents, during several years, a crucial need allowing organizations to improve their decision-making processes, in order to enhance the success of their activities and thus their sustainability. For decision-makers, analyzing the contents of documents represents a real challenge. In this context, we propose a new and generic multidimensional model called CobWeb; it is based on the galaxy model and dedicated to the OLAP (On-Line Analytical Processing) of XML documents (eXtensible Markup Language). The proposed model relies on a combination of different standard facets extracted from XML documents in order to provide more opportunities for the expression of analytical queries and an appropriate vision of data for decision-makers.
