Tim Berners-Lee, 1999

“I have a dream for the Web [in which computers] becomecapable of analyzing all the data on the Web – the content, links,and transactions between people and computers. A ‘SemanticWeb’, which should make this possible, has yet to emerge, butwhen it does, the day-to-day mechanisms of trade, bureaucracyand our daily lives will be handled by machines talking tomachines. The ‘intelligent agents’ people have touted for ages willfinally materialize”
