Dave Raggett

Dave Raggett is an English computer specialist who has played a major role in implementing the World Wide Web since 1992. He has been a W3C Fellow at the World Wide Web Consortium since 1995 and worked on many of the key web protocols, including HTTP, HTML, XHTML, MathML, XForms, and VoiceXML. Raggett also wrote HTML Tidy

In 1993, Raggett devoted his spare time to developing a Web browser called Arena, on which he hoped to demonstrate new and future HTML specifications. Development of the browser was slow because Raggett was the lone developer and Hewlett-Packard, like many other computer corporations at the time, was unconvinced that the World-Wide-Web would succeed, and thus did not consider investing in web browser development.

In Weaving the Web: The Original Design and Ultimate Destiny of the World Wide Web by its inventor, Tim Berners-Lee wrote: One of the few commercial developers to join the contest was Dave Raggett at Hewlett-Packard in Bristol, England. He created a browser called Arena. HP had a convention that an employee could engage in related, useful, but not official work for 10 percent of his or her job time. Dave spent his 10 percent time, plus a lot of evenings and weekends, on Arena. He was convinced that hypertext Web pages could be much more exciting, like magazine pages rather than textbook pages, and that HTML could be used to position not just text on a page but pictures, tables, and other features. He used Arena to demonstrate all these things, and to experiment with different ways of reading and interpreting both valid and incorrectly written HTML pages.

Raggett demonstrated the browser at the First International Conference on the World-Wide Web in Geneva, Switzerland in 1994 and the 1994 ISOC conference in Prague to show text flow around images, forms, and other aspects of HTML later termed as the HTML+ specification. Raggett subsequently partnered with CERN to develop Arena further as a proof of concept browser for this work. Using the Arena browser, Raggett, Henrik Frystyk Nielsen, Håkon Wium Lie, and others demonstrated text flow around a figure with captions, resizable tables, image backgrounds, HTML math, and other features.

In 1994, Raggett organized a Birds of a Feather (BOF) on HTTP, and went on to launch and chair the IETF HTTP working group, as well as driving early standards work on HTML+, HTML 3.0, HTML tables, and working with NCSA on the design of HTML forms.

From 2000 to 2003, Raggett worked at Openwave Systems as a technical manager for Openwave's involvement in W3C and W3C Fellow (member of W3C staff). Openwave had experience with VoiceXML for unified messaging. They also planned to add mobile support for multimodal services, but had to refocus due to a downturn in telecoms spending by mobile operators.

In the next three years, he worked at Canon as a consultant working on driving the evolution of standards for multimodal interaction and other W3C technologies.

From 2006 to 2007, Raggett worked at Volantis as a principal researcher working on standards and related proof of concept implementations, focusing on standards work on the Ubiquitous Web.

The term Virtual Reality Modeling Language (VRML) was coined by Raggett in a paper submitted to the First International Conference on the World-Wide Web in 1994, and first discussed at the WWW94 VRML BOF established by Tim Berners-Lee, where Mark Pesce presented the Labyrinth demo he developed with Tony Parisi and Peter Kennard.

Specifications/Protocols Specifications and protocols written and developed by Raggett include: XForms HTML+/3.0/4.01 XBRL
