In this week’s meeting (10-11am Tue, April 21), Ankur Padia will present work in progress on providing access control to an RDF triple store.

Triple store access control for a linked data fragments interface
Ankur Padia, UMBC

The maturation of Semantic Web standards and associated web-based data representations such as schema.org have made RDF a popular model for representing graph data and semi-structured knowledge. Triple stores are used to store and query an RDF dataset and often expose a SPARQL endpoint service on the Web for public access. Most existing SPARQL endpoints support very simple access control mechanisms if any at all, preventing their use for many applications where fine-grained privacy or data security is important. We describe new work on access control for a linked data fragments interface, i.e. one that accepts queries consisting one or more triple patterns and responds with all matching triples that the authenticated querier can access.
