The Third Wave

According to Nova Spivack, the next generation of web technology, known variously as the semantic web and Web 3.0, is closer than you think. He has started a company that aims to exploit the next generation of web technology, and he expects to launch his first product this year. Radar Networks, the San Francisco startup Spivack, 37, heads, is in stealth mode, and he won't say exactly what it has planned except that it won't compete directly with Google. "We're working on a different strategy," he promises. "It's a game-changing one."

The idea behind the semantic web is to make data on web pages and in online databases better able to be read and understood by computers and used and shared by different software applications. "The semantic web will do for data what the web did for documents," Spivack says. "It will make it universally searchable and sharable." The standard way to organize and present data on the semantic web is described by the Resource Description Framework, or RDF, which plays a role on the semantic web similar to the one HTML plays on the original web.
