W3C is holding a workshop in Dublin, Ireland on 5-6 June on web authoring techniques that reduce the need for scripting through the use of modeling techniques. We hope to tap into the academic research work on user interface and application modeling, and the potential for describing applications from an end to end perspective, rather than just the pieces that are downloaded to a particular browser. On the desktop, developers need to contend with several different versions of several different browsers, each with different levels of support and different bugs. The situation is very much worse for mobile devices and this presents real challenges to developing and delivering web applications with limited budgets. In principle, this can be addressed by describing applications at a level that is decoupled from the details of specific devices, and the use of policies that separately describe how to adapt the presentation and behavior to match these devices. W3C has made some steps in this direction with work on device independent authoring languages, device descriptions and the means to select markup or style rules according to the context. However, there is plenty of potential for markup languages that describe applications at a level that includes both client and server, e.g. based upon event-driven state models. As more and more devices are gaining some kind of networking capability, there is an opportunity to apply web technologies to describing multi-device applications, e.g. using a digital TV or mobile handset to access and control household appliances, home entertainment, security and surveillance systems. What kinds of models are appropriate for such distributed web applications? When it comes to access to device capabilities and services, what kinds of security models are appropriate and how can these be made sufficiently usable to work in practice? Examples include access from within a web browser to the device's built-in camera, or the means to remotely unlock the front door of a building. The Semantic Web would seem to offer promising techniques for descriptions of devices and services as a basis for discovery, and policies for access control. The Web is still in its early days and there remain significant challenges for improving the way in which we author Web applications, however these also represent huge opportunities. W3C welcomes you to come to Dublin, the capital of Ireland and the epicenter for Guiness lovers everywhere, to participate in the workshop on declarative models of distributed web applications. If you are interested in participating, please send us a brief statement of interest to team-ubiwebws-submit@w3.org Further details can be found at: http://www.w3.org/2007/02/dmdwa-ws/ Dave Raggett <dsr@w3.org> http://www.w3.org/People/Raggett
