Formal ontologies are explicitly representation of domain knowledge. Ontology change management should ensure maintaining its consistency, so that its users can continue to cooperate and understand each other. This paper presents a meta-conceptual modeling approach for change modeling in the domain of applied ontology. This modeling approach makes use a mathematical structure to model ontologies and its changes in order to make possible the qualification of changes regarding its consistency. Actually, the paper focuses on the meta-conceptual modeling approach inspired by Guarino's formal ontology building process.
