Presentation slides for Standards.next event (http://standards-next.org) on June 12, 2010. These slides cover a number of topics related to Web standards on mobile, including widgets, device APIs, HTML5, and geolocation.

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

2. Who am I?
• Web standards guy (W3C Advisory Committee Rep) at Vodafone
• Co-chair of Mobile Web Best Practices, Social Web Incubator Groups
• Member of the TAG

3. 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)

4. but...

5. • 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

6. “HTML5” on Mobile
• HTML5 is a buzzword, and that’s OK
• Canvas, SVG, Video, Audio
• Off-line operation (appcache)
• Web storage
• Gestures (iGesture jquery plugin)

7. 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 environments: Vodafone 360; Nokia widgets; Opera

8. 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)

9. APIs

10. APIs
(are sexy)

11. 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
• Firefox, Safari, Chrome, iPhone, Android
• 21 Commerical services identified using it
• Examples: Google Maps, Local Search, Flickr, Travelocity, Identi.ca, etc...
• Many other sites using Gears Geo API

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

13. CycleStreets!

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

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

16. • 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

17. W3C Workshop on “Privacy for
Advanced Web APIs”
• Mid-July in London
• novel approaches and architectures toward privacy on the Web
• implementation experience with current generation device APIs
• deployment experience of current generation device APIs
• implementation and deployment experience from a public policy perspective
• policy considerations for the future development of the Web platform in general, and
advanced APIs in particular
• user experience and service design issues and approaches
• social or regulatory issues relating to privacy as they potentially impact any of the above

18. What about Augmented Reality?
• W3C Workshop on AR and the Web - next week in Barcelona
• How does the Web relate to AR?
• Can Web browsers become AR platforms?
• Content Display + Style + Script + GPS + Sensors + Camera Access
• What’s the relationship between AR and linked data?
• W3C Augmented Reality Incubator Group? Watch this space...

19. Mobile Web Application Best Practices
• Good advice on how to build great mobile WebApps now from W3C
• We need “implementation reports” and feedback
• http://www.w3.org/TR/mwabp/

20. 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, lots of demos at Google I/O
