Collaborative research requires flexible and fine-grained access control, beyond the common all-or-nothing access based purely on authentication. Existing systems can be hard to use, and do not lend themselves naturally to federation. We present an access-control architecture which builds on RDFs natural strength as an integration framework, which uses RDF scavenged from X.509 certificates, and policies expressed as ontologies and SPARQL queries, to provide flexible and distributed access control. We describe initial implementations.
