W3C Work On Semantic Web Draws Criticism""If I can make sure that all of my trading partners and all of my systems in my divisions are speaking the same language, that that will solve 90 percent of my problems," Ronald Schmelzer, analyst for ZapThink LLC, said. "People are not at the point where they need to talk to arbitrary systems that they don't know the semantics for."... But W3C spokeswoman Janet Daly said RDF technologies are in use today by AOL Time Warner Inc., Hearst Corp. and LexisNexis. The W3C work is enabling companies to build applications with more sophisticated search capabilities. The group's Web services and Semantic Web technologies are complementary, Daly said. "They actually work hand-in-hand.""
