Data warehouses are based on multidimensional modeling and OLAP. Checking multidimensional models and their summarizability is complex and error-prone. To perform this task, formal reasoning is appropriate. In this paper, we propose and illustrate an approach to represent a multidimensional model as an OWL DL ontology, and reason on this ontology to check the multidimensional model and its summarizability. We also investigate the complementarities between our approach and the RDF Data Cube vocabulary, in order to facilitate transition to the semantic Web.
