Tim Berners-Lee on Web 2.0 (and other topics): “Mash-ups are called Web 2.0, but they are data integrations – taking a piece of display technology like a map application and doing a handcrafted data integration. I’ve yet to see a mash-up that uses semantic Web data and crafts it – the fact that everyone has their own mash-up tells the story. What I’ve always wanted to do is take an arbitrary thing, a data file, and if it’s got something that can be mapped, drop it into a map and see what occurs without programming.” (BCS)
