http://www.w3.org/ -- 16 May 2006 -- Today, the World Wide Web Consortium announces the publication of the Device Independent Authoring Language (DIAL), which facilitates authoring for an ever-expanding range of mobile devices. The W3C Device Independence Working Group invites review and discussion with the community of this First Public Working Draft.
"The DIAL suite makes the most of existing, established Web technologies and principles, and extends their reach with new features that better serve the needs of diverse devices", explained Working Group Chair Rhys Lewis of Volantis. "Born of expertise from device manufacturers, software vendors, mobile operators, content companies and the accessibility community, DIAL has potential to improve the quality of mobile life."
Thousands of mobile devices with a wide range of capabilities are in use today. People have come to expect the same quality of service and wealth of information available on the move that they find on the Web at their desktop computers.
This diversity poses significant challenges to Web designers and mobile operators alike. How does one create content for upwards of 2,500 different kinds of mobile devices? How do operators deliver that content in ways that are both efficient and pleasing to the customer?
The DIAL approach to meeting these challenges is tried and true: content is more flexible and adaptable when data, styling, layout, and interaction are described independently.
DIAL is a language profile based on existing W3C XML vocabularies and CSS modules. These provide standard mechanisms for representing Web page structure, presentation and form interaction. DIAL also makes use of the DISelect metadata vocabulary for overcoming authoring challenges inherent in authoring for multiple delivery contexts.
DIAL has been developed within W3C by the Device Independence Working Group, which includes industry leaders such as ANEC (European Association for the Co-ordination of Consumer Representation in Standardisation), The Boeing Corporation, CNR--Consiglio Nazionale delle Ricerche, Electronics and Telecommunications Research Institute (ETRI), France Telecom, IBM Corporation, Mobileaware, Ltd., Nokia, Segala, Vodafone, and Volantis Systems Ltd,
The work of the Device Independence Working Group serves as part of the technical foundation for W3C's Mobile Web Initiative (MWI), making the vision of "one Web" for all devices a reality.
The World Wide Web Consortium (W3C) is an international consortium where Member organizations, a full-time staff, and the public work together to develop Web standards. W3C primarily pursues its mission through the creation of Web standards and guidelines designed to ensure long-term growth for the Web. Over 400 organizations are Members of the Consortium. W3C is jointly run by the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) in the USA, the European Research Consortium for Informatics and Mathematics (ERCIM) headquartered in France, Keio University in Japan, and has additional Offices worldwide.
