    schema:text "It is a period of hidden value. In 1965, TED NELSON named it HYPERTEXT. At Brown University, ANDY VAN DAM made it work. DOUG ENGELBART showed it to the world. Yet for nearly thirty years, the market looked the other way. Then, at CERN, TIM BERNERS-LEE broke the platform boundary with URLs, HTTP and HTML. MARC ANDREESSEN's MOSAIC and NETSCAPE let people simply click, and the Web of Documents swept the world. Now a second journey, again led by TIM BERNERS-LEE, reaches its turning point. Since 1999, RDF, LINKED DATA and ONTOLOGIES have waited for an interface worthy of the architecture they hold. That interface has arrived. LLM-powered AI AGENTS are turning HYPERDATA into everyday utility, kept honest by identifiers, semantics and provenance, and the Semantic Web Project is being vindicated, one natural-language question at a time."@en ;
