The ontological change, understood as the process that allows to represent, implement, maintain and propagate the update of an ontology, it is managed mainly from two perspectives: version control and ontological evolution. Among the alternatives proposed management is supported management in conceptual models, where abstraction implementation language used in the construction and deployment of ontology is made. This paper presents Ontoconcept a tool to manage change in a ontology from this perspective, apart from the implementation language in which the ontology is built. The tool has been built in the laboratory of the Research Group on Artificial Intelligence GIA of Technological University of Pereira, and is supported on the theoretical model developed in the doctoral thesis of the author.
