"A lot of people assume that Semantic Web consists only of the metadata, the data at the top of an article that indicates who it was written by. But no, it's the data. It's the government spending data. It's where the potholes are and where space ships are. It's where cars are. It's where taxis are and it is all the data that makes a map. It's the data that makes all the charts, and it's the data that makes industry run. It's the data that makes governments run. It's not just metadata, and it's not data just sucked from the Web."
