Forgetting with SPARQL, and Remembering, too

SPARQL is an RDF query language suitable for adding and deleting facts. Not all facts, however, should be forgotten forever. For example, developing an electric car, one might want to benefit from previous experiences of building a car with conventional gas engine, but this previous experience should force you to add a silencer to your electric car, since this is not needed. As a solution, we envision the ranking of facts and the manipulation of this ranking using the SPARQL update and query language.
