Mobile Web Application Best Practices

• The Web has grown from a page-based metaphor into a full-blown application platform

• Most things you used to need a special application for you can now do on the Web

Widgets

• Take Mobile Web Applications to the next level

• Build mobile applications using Web technologies familiar to millions of developers

• Package these Web applications up in a standard cross-platform way (W3C)

• Enable these applications with (secure) access to device capabilities through APIs

• Deploy into a Web Run-Time environment (analogous to a Web browser, but windowless and integrated into the device UI)

• Create a clear proposition for the developer and a route to market

• Cross-platform mini-applications, built on open Web standards that are easy to write and deploy and leverage a well-understood security model

Mobile Widget Programme11

Widgets Extend the Web

• Widgets use existing Web technologies– HTML, JavaScript, CSS

• Packaging and configuration standards being developed in W3C– In development in Web Applications working group

• Complimentary to off-line capabilities of HTML5

• Widgets may be updated automatically

• Access to device capabilities will be standardized as well– W3C Geolocation API working group – referenced by OMTP BONDI, already

implemented in iPhone 3.0 browser, Android, Opera test builds, Mozilla…– OMTP BONDI interfaces

Widgets are at the epicenter of the Mobile <-> Web Convergence

• Widgets are part of the Web ecosystem

• Fragmented implementations are out there especially around APIs and security model– Nokia widgets, Opera Widgets, BONDI widgets, JIL widgets, etc…

• New W3C Device APIs working group working on one agreed set of APIs– All players at the table: Opera, Nokia, Vodafone, BONDI, Google, Mozilla, Microsoft– Nokia and Vodafone co-chairing this effort– Delivery probably in 2010
