This document discusses Richard Wallis and his work extending the Schema.org vocabulary. It notes that Wallis is an independent consultant who founded Data Liberate and currently works with OCLC and Google. He chairs several W3C community groups focused on extending Schema.org for bibliographic and archive data. The document outlines how Schema.org was created in 2011 as a general purpose vocabulary for describing things on the web and how it can be extended through groups like the Schema Bib Extend community to cover additional domains beyond its original 640 types.
