| http://www.w3.org/ns/prov#value | - So when a student writes that ???John F. Kennedy was assassinated on November 22, 1963 in Dallas, TX,??? and cites Wikipedia as the source, I tell that student ???no citation necessary ??? common knowledge.??? Does that mean everybody knows the answer, sort of like the sky is blue, or does it mean that the answer can be obtained online in less than ten seconds?
