RAP: RDF Access-control Policies.

RAP looks at solving the problem of defining and implementing Access Control for a RDF store. The work involves expressing these controls using and implement a prototype. The basic RAP framework will allow an agent (person or program) to perform various actions inserting, deleting, searching on a RDF store and the policy is used to decide if the action is permitted or prohibited. Some of the aspects to be dogged are, how to represent the policies (REI, N3, Prolog ... etc), what level of granularity of access control is needed, how performance would be affected in a store with RAP, How delegation of creation of policies should be handled etc
