Also here’s another article on semantic web – this one more of a technical primer. I’m a bit over my head with the semantic web stuff and should probably get back to writing about visualization. But, when semantic finally takes off there will be such an enormous amount of strucuted data that a lot is going to change – business models will change, the need for visualization will increase (see? this post is on topic), there will be a big increase in connectedness – (which for me is the coolest thing about Google Earh – there’s maps, and webcams, and overlays and they all work together). Ten years ago, when I started doing visualization, the biggest problem was there was no data. The amount of data has changed dramatically in the last 10 years. And semantic web will increase it a lot more.
