Jeffrey Zeldman speaks with Tantek Çelik, web standards lead at Mozilla.
Currently web standards lead at Mozilla, Tantek is one of the founders of both the microformats.org open standards community and the Global Multimedia Protocols Group, and an invited expert to the World Wide Web Consortium (W3C) Cascading Style Sheets working group.
Tantek has played a key role in the development and popularization of practical social network portability technologies such as the hCard and XFN microformats. In 2003, Tantek collaborated with Eric Meyer and Matt Mullenweg in the invention of the XHTML Friends Network (XFN), which has since become the most popular decentralized social relationship format in the history of the Web. In 2004 Tantek proposed hCard for representing people and organizations, which has since similarly become the most popular user profile format on the web.
During his years as Technorati’s Chief Technologist, Tantek played an active role in refining and evangelizing hCard, bringing it from a wiki proposal to one that’s endorsed and supported by individuals, numerous small organizations, major companies ranging from AOL to Yahoo, and implemented for over a hundred million user identities and business listings on the web.
At Microsoft, Tantek led the development of Internet Explorer 5 for Macintosh and its Tasman rendering engine, which was the most standards-compliant layout engine of its time. He was also an early member of The Web Standards Project, and is the creator of the Box Model Hack, the first IE hack that let developers work around the incorrect box model in old versions of Internet Explorer.
