Abstract. Ontology-based data access has received a lot of attention recently, yet there is no clear methodology to evaluate a “semantically enriched ” information system in general or an ontology based data access system in particular. The quality of such an information system clearly depends on how well your data fits your class-level ontology, and how well these two components fit your queries. This paper presents a generic, flexible framework for this kind of analysis: it can be used, e.g., to compare two class-level ontologies w.r.t. their fitness for a given kind of data and query set. We apply the framework to an example case and show how it helps to answer relevant modelling and representation questions. 1
