Abstract
In this paper we examine how Discretionary Access Control principles,
that have been successfully applied to relational and XML data, can be applied
to the Resource Description Framework (RDF) graph data model. The objective
being to provide a baseline for the specification of a general authorisation
framework for the RDF data model. Towards this end we provide a summary of
access control require- ments for graph data structures, based on the divergent
characteristics of graph models compared to relational and tree data models. We
subsequently focus on the RDF data model and identify a list of access rights based
on SPARQL query operations; propose a layered approach to authorisation
derivation based on the graph structure and RDFSchema; and demonstrate how SQL
GRANT and REVOKE commands can be adapted to cater for delegation of privileges
in SPARQL.
