Ontology engineering gets vital importance after the idea of semantic web. The huge amount of data on current web makes information retrieval most difficult and complex process. This problem brings the idea of semantic web in which data will be in a structured form so that machine can understand and integrate data from different sources to retrieve required information for the end user. Ontology makes this possible to have data in structured form, so success of semantic web heavily depends on the successful development of ontology. Ontology development from scratch is most difficult and time taking process. So there is need to use existing, mature and accepted object oriented models of software engineering for development of ontology.
