However, this practice makes data level integration quite hard, and definitely prevents the straightforward application of RDF graph merge for independently developed knowledge bases, even if they share the same OWL ontology. In this paper, we present a Protege plugin which supports the systematic reuse of global identifiers for instances in RDF/OWL knowledge base. The plugin is an extension of the "individual" tab. The main difference is that, when an instance is created, the user has a chance of looking for a pre-existing URI for the corresponding individual in a publicly available service called OKKAM. The match between the newly created instance and the stored individuals is based on an algorithm which compares the features of the new isntance with a simple profile stored in OKKAM for all individuals. The plugin is available and tested for Protege 3.2.1.
