Things have changed significantly since those early days. structured data is now published on over 10 million web domains; the vocabulary has expanded to include over 600 Types and nearly 1,000 Properties; it’s core capability for describing bibliographic resources has been greatly extended.

Join Independent consultant Richard Wallis, former Technology Evangelist for OCLC, currently working with Google on, for this two part, in-depth mini-series look at, its use, and extension in the bibliographic and wider domains beyond.
