Axioms on a semantic model for legislation for accessing and reasoning over normative provisions

In this paper an approach to the Semantic Web in the legal domain is presented: it is obtained by modelling legislative document semantic profiles using a model of normative provisions. An implementation of this approach through RDF/OWL, describing provisions and their relations, is proposed. In particular, a pattern able to implement Hohfeldian legal fundamental relations between provisions using OWL-DL expressivity is described within a case study involving duty and right provisions. An example of advanced access and reasoning over provisions using the proposed approach is shown.
