Abstract

In this paper we examine the notion of ontology evolution. Within a framework of generic ontology we suggest that the evolution of an ontology can be modelled more comprehensively and efficiently by identifying the elements of ontology change. Many of these fundamental units of ontology change are dependant on the ontology language. Here we describe these elements of change for the Web Ontology Language (OWL) by defining an extension of OWL called DOWL.
