1. It’s the Web
(but not as we know it)
The Rise of Mobile, Web Run-Times and APIs
Daniel Appelquist (@torgo)

2. The (mobile) Web Today
• 28.6% of (U.S.) mobile subscribers using the mobile browser (Comscore)
• Developers defecting from App Store to HTML5 (ZDNet)
• Apple: 40%, Nokia: 16%, Samsung: 10%, Motorola: 7.6%, HTC: 5%... (AdMob)
• “Mobile Touch Web” Growing:(Taptu)

3. but...

4. • You can’t access device information (location, contacts, camera, etc...)
• You can’t build rich interactivity
• User needs to be connected in order to get to the Web
• User interface is clunky (launch browser, go to bookmarks, etc...)
• No (easy) way to monetize webapps

5. Interactivity & Graphics
• Canvas
• SVG

6. W3C Widgets
• Package up a web application using a well-known format (“P&C”)
• Download and install (“install event”)
• Specify required permissions (“WARP”)
• Run in a “web runtime” environment
• Automatic Updates (“Widgets Update”)
• Cool open source implementation (Apache Wookie - http://getwookie.org)
• Real deployment environment: Vodafone 360; Nokia widgets; Opera

7. Widgets and HTML5
• Widgets can use HTML5
• Widgets is a different take on off-line from HTML5 Appcache
• “HTML5 Apps”* WebApps written in HTML5 packaged up as Widgets
• Use Phonegap to package these as iPhone apps (for legacy purposes)

8. APIs

9. APIs
(are sexy)

10. Web Location: the W3C Geo API
• Based on original input from Google, working group also included Mozilla, Opera,
Microsoft and Vodafone
• Work is complete, already embedded in shipping browsers: iPhone, Firefox 3.5+
• 21 Commerical services identified using it
• Examples: Google Maps, Local Search, Flickr, Travelocity, Identi.ca, etc...
• Many other sites using Gears Geo API

11. Why is Location Sexy?
• Because you can find Burger King
• Refine search
• Add location to any Web App
• Apps like Gowalla are already on
the Web (m.gowalla.com)

12. W3C Device APIs
• Contact Book • Device Interface
• Calendar • System Info & Events
• Filesystem • Gallery
• Capture Audio / Video • Tasks
• Messaging • App Launcher

13. Privacy
Who gets to use all this data and for what purposes?

14. • Appropriateness: Is the collection of information appropriate to the app?
• User Control: How much control does the user have over how their info is
used?
• Notice: Is the user getting enough notice that information is being collected?
• Consent: Is the user in control of decisions to disclose information?
• Secondary Use: Is user consent required for secondary use? (e.g. ad targetting)
• Distribution: Is information being re-transmitted to other parties?
• Retention: How long is data retained?
• Transparency and Feedback

15. Location Privacy

16. Mobile Web Application Best Practices
• Good advice on how to build great mobile WebApps now from W3C
• We need “implementation reports” and feedback

17. OneSocialWeb
• Open source, distributed platform for social networking
• Based on XMPP and ActivityStreams + extensions
• Enables social interactions, with access control, between social
systems with no a priori knowledge of each other
• Debuted at FOSDEM conference last month
