Elected member • W3C Technical Architecture Group (TAG)
The TAG reviews new Web technologies, and authors the underlying architectural principles of the Web. It is a small group of only 8 elected and 3 appointed members, including creator of the Web, Tim Berners-Lee. A passing TAG review is required for a new technology to ship in Google’s Chrome browser. My work in the TAG is sponsored by the OpenJS Foundation.
