CNN: A pair of German researchers have designed a prototype kiosk that gives iPhone users their first taste of the semantic Web. The semantic Web is just one component of what many tech analysts are calling "Web 3.0" -- the next generation of online interaction. Generally, it refers to an　emerging　Internet experience in which all things on the Web will be described with descriptor languages so computers can "understand" what they are. An object marked as baseball bat could be identified by the computer and the Web could immediately display related data, such as information on catchers' mits, baseballs, uniforms, etc.　After the user　places his iPhone on the kiosk surface, a circle appears around it displaying -- among other things -artists and albums similar to the MP3 tunes loaded on the iPhone.
