Tim Berners-Lee has described the semantic web as a component of ‘Web 3.0′.

“People keep asking what Web 3.0 is. I think maybe when you’ve got an overlay of scalable vector graphics – everything rippling and folding and looking misty — on Web 2.0 and access to a semantic Web integrated across a huge space of data, you’ll have access to an unbelievable data resource.”

– Tim Berners-Lee, 2006
