Ontology is one of the layers of the semantic web architecture, the need for which arose in the semantic web because machines were not able to understand the meaning of the content of text as seen by the humans. There are authoring and ontology development tools available that don’t require the user to write in the ontology in OWL syntax. One such tool is Protégé. Protégé can be customized to provide domain friendly support for creating knowledge models and entering data. In this paper, an example of using Protégé showing two ways of modeling ontologies, understanding its frame-based editor method and using the OWL editor is given.
