Ontology as an Information Base for Domain Oriented Portal Solutions

Abstract. Ontologies are becoming increasingly accepted as a form for information representation of distributed web-based information and its processing. In our paper we build a web-based application around an ontology, which serves both as a data base and metadata source used in processing of the data. We propose techniques and methods that exploit this metadata to provide an easy and flexible implementation of the CRUD pattern. We identify patterns in the ontological representation of domain entities and transform them into web-based forms for data management. Based on this flexible framework we can model variations to adapt the application for specific sub-domains.
