Executive Summary

The research community has noted the need to retrieve the instance level of an ontology from bulk data stored in external data sources (e.g., a relational database), in order to delegate to the external source all aspects of the actual management of the data.

However, existing DL reasoners cannot properly deal with such ontologies.
