Ontology databases in Semantic Grid can grow very large making it more complex and difficult to manage. Sub-ontology extraction in compliance with the user requirements paves the way for sub-ontology reuse in sub-ontology/ontology tailoring. As new developments and discoveries are unleashed, or when sub-ontology will be reused, the need to update the extracted sub-ontology is deemed necessary. In this paper, we proposed a sub-ontology update mechanism and verify its functionality and performance. Preliminary results demonstrate the viability of the proposed mechanism.
