Towards Dynamic Ontology - Integrating Tools of Evolution and Versionning in Ontology

6; International audience; Since Gruber's definition, a lot of works focused on evolution or versioning issues. Not much attention has been paid to integrated solutions which resolve both these two purposes. In this paper we present a new semantic architecture that combines versioning tools with the evolution process. This architecture called VersionGraph is integrated in the source ontology since its creation in order to make it possible to evolve and to be versioned.
