Towards a definition of an Image Ontology

Archiving, organizing, and searching multimedia data in an appropriate fashion is a task of increasing importance. The ontology theory may be appropriately extended in order to face this challenging issue. In this paper we propose an extension of an Image Database model based on NF2 with an Ontology model. We first describe NF2 and the main concepts of Image Ontologies, then we propose a general architecture for supporting creation and management of multimedia objects.
