The document discusses Richard Wallis and his work extending Schema.org to better describe bibliographic data. Wallis is an independent consultant who chairs several W3C community groups focused on expanding Schema.org for bibliographic and archives data. He has worked with organizations like OCLC and Google to develop vocabularies that extend Schema.org to describe over 330 million bibliographic resources in linked data.
