Future of IT: Web 3 0 and Web 4 0 will make social sites look quaint: "With his 27-year government career, Brand Niemann, co-chairman of the Semantic Interoperability Community of Practice, seemed a likely choice to reflect on the past and future of government computing and what’s ahead for social networking and the Web.

Semantic interoperability — the ability of information systems to exchange data using a common vocabulary to guarantee that concepts and their interrelationships are not misinterpreted — is just one example Niemann cites of how technology can support data sharing. He sees the future of government computing as a place where knowledge is shared."
