Sir Tim Berners-Lee (born 1955) is a British computer scientist who invented the World Wide Web in 1989 while working at CERN. He designed HTML, HTTP, and URLs — the three pillars of the web’s architecture — and founded the World Wide Web Consortium (W3C) to develop open standards.

Core ideas

  • The web as a universal information space: Berners-Lee designed the web to be platform-independent, decentralized, and open — anyone could publish, anyone could link, no central authority controlled the content (Berners-Lee, 1999).
  • linked data: in 2006, Berners-Lee articulated four principles for publishing structured data on the web so that machines and humans can follow connections across sources. This is the foundation of the semantic web.
  • The semantic web: an extension of the document web in which information carries machine-readable meaning, enabling automated reasoning across linked datasets (Berners-Lee et al., 2001).
  • Web standards and openness: through the W3C, Berners-Lee has advocated for open, royalty-free standards as the basis for web technology.

Notable works

  • Weaving the Web (1999)
  • “The Semantic Web” (2001, with Hendler and Lassila)
  • “Linked Data” (2006, design note)
  • linked data — the principles he articulated for structured web data
  • semantic HTML — the markup language he created
