This paper offer a new approach for using Conceptual Modeling in ontologies instead of simple Description Logic. The idea is to use the Extended Entity-Relationship (EER) models, which are seen as offering the richest semantic expressiveness. This technique is seen as an advantage for humans and for Agents as well, because they can explore a conceptual schema without going trough a long list of DL axioms.

An interesting research direction for the data structures is said to be the spatio-temporal extension of DL languages.
