Improved Database Schema Development for OWL2
Abstract
This paper proposes a novel approach to storing ontologies in relational databases. The approach consists of a database schema, which was created to be capable of storing ontology information defined in OWL2 (Web Ontology Language 2) functional syntax. The paper explains how the schema has been designed and what advantages it offers to any user. The described schema is part of a larger system. This paper also discusses how the schema cooperates with the external system, which, however, is outside the scope of this paper, to successfully create, store and retrieve ontology knowledge from the functionality offered by the relational database. Further, this paper describes the implementation of the proposed method in prototype software. The described schema shall be the first step of the creation of an ontology-based database access system.
