2007-09-11: The World Wide Web Consortium today released GRDDL and GRDDL
Test Cases as Recommendations. GRDDL enables authors to extract data from
their documents automatically, enabling them to reuse their data and enrich

the GRDDL Primer, the press release and testimonials, and about the Semantic
Web.
