Question is for the Presentation: Abel2007enabling presented by Tim Lebo 25 sept 2008
Question is asked by: Joshua Taylor
The Question is: Is there any provision made for whether restricted triples may be indirectly accessed? For instance, A query could be posed asking for individuals ?x and ?y where ?x hasPhone ?z and ?y hasPhone ?z. If both Joe hasPhone 555-5555 and Mary hasPhone 555-5555 are restricted, then answering the aforementioned query would be permissible since even answering with ?x ↦ Mary, ?y ↦ Joe wouldn't even indirectly allow either restricted triple to be reconstructed. While this example might seem contrived, it is easily conceivable that with a sufficient number of joins, restricted triples could be used without the particular triples being available from the end result.
