Abstract. In recent years a lot of effort has been put into research dealing with accessing relational data with the help of ontologies. Solutions related to this issue focus on the Ontology-based Data Access (ODBA) architecture. Therefore the family of DL-Lite formalisms and in particular DL-LiteA has been developed to enable ontology design for efficient processing of conjunctive queries targeting a large amount of data stored in relational data bases. However, due to strong limitations and the comparatively high complexity of constructs comprised by DL-LiteA, it can be quite a challenging task to design ontologies which are based on this formalism. This paper presents an editor for DL-LiteA fulfilling ontology design. Thanks to its features, such as automated generation of axioms, on-the-fly inferring and graphical representation of relations between concepts, the editor simplifies the design process and improves the quality of the resulting ontologies significantly. The application and evaluation of the editor in two projects on data and knowledge integration for energy saving and urban planning confirmed these advantages.
