Ontology evolution is a complex problem. In our work, we focus on issues related to change management, particularly consistency maintenance and we present in this paper, an overview of Change Management Patterns (CMP) that we have defined to model the three dimensions change, inconsistency and resolution alternative. Modelling these patterns and the links between them, helps to propose an automated process guiding and controlling change application while maintaining consistency of the evolved ontology. Change management depends closely on the ontology representation model, we focus on OWL language and we consider change impact on logical consistency as specified in OWL DL layer.
