OLS: An Ontology Based Information System

This paper presents a design ontology that deals with the hypermedia presentation aspects involved in the development of a Semantic Web Information System. The ontology is driven by two main design models: the Conceptual and the Application models. The application model extends the conceptual model with presenting data and inferring. During the presentation generation the input data goes through a sequence of transformation steps. Using Semantic Web technology we chose to represent the models and their instances in OWL  DL. Protégé 3.2[16] and some of its plug-ins are used to develop this experiment. In this study we’ll implemented an Ontology Based Information System in web environment and query this ontology through web interface.
