    • Agenda
      • Introduction to Blueprint
      • Mobile Widgets Development Process
      • Q & A
    • Introduction to Blueprint
    • The Problem - Device Fragmentation Multiple brands – multiple phone models Multiple operating systems Different screen resolutions Different memory capabilities Providing the best user experience is not easy
    • Browser Grades Apple iPhone, HTC Dream HTML4/5, CSS, Javascript, unlimited A (Hero) Motorola q9, Samsung T919 HTML4, CSS, 50KB page A Blackberry Curve 8310, Nokia N70 XHTML, CSS, 30KB page B Nokia 3110c, SonyEricsson W200a XHTML, 30KB page C Nokia 6085, Motorola RAZR vc XHTML, 16KB page D Samsung R450, Motorola i576 XHTML, 9KB page E Motorola RAZR v3, Nokia 2610 XHTML, no images, 9KB page F Nokia 3510i, Motorola i355 WML-only, not supported by Blueprint X Examples Definition Grade
    • Where are we now?
    • Device Quirks Examples
      • OperaMini does not understand some CSS selectors
      • Blackberries do not understand most CSS anyway
      • Motorola V3 has an 8K page limit
      • Some Nokias won't show tables unless you specify a doctype
      • A Sidekick browser canvas width loses about 20 the doctype is an XHTML type
      • Samsungs/Sharps tend to have a strange understanding of what “100% width” is
      • Pocket Internet Explorer… need I say more?
    • Blueprint Mobile Platform Open Simple Maximum Reach Free!
    • Blueprint Language
      • Is an XML markup set based partly on XForms
      • Is a purely declarative language – includes no scripting or procedural code
      • Abstracts the developers from the device details and allows them to quickly develop mobile web sites that adapts across devices
      • Blueprint platform transcodes the blueprint markup for different devices, making sure that it renders properly and nicely
    • Blueprint is simple <page style=&quot;collection&quot;> <content> <module> <header layout=&quot;simple&quot;> <layout-items> <block class=&quot;title&quot;>Greeting</block> </layout-items> </header> <block>Hello World!</block> </module> </content> </page>
    • Even for some more complex presentation <?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?> <page style=&quot;collection&quot;> <page-header> <title-bar> <title>Restaurants</title> <commands> <ui-command> <title>Home</title><load event=&quot;activate&quot; resource=&quot;#&quot;/> </ui-command> </commands> </title-bar> </page-header> <content> <module class=&quot;featured&quot;> <header> <layout-items><block class=&quot;title&quot;>Featured Restaurant</block></layout-items> </header> <placard layout=&quot;card&quot;> <layout-items> <image size=&quot;xx-large&quot; resource=&quot;widget:bp11examples/images/Thai_Seafood_Curry.jpg&quot; caption=&quot;Seafood curry&quot;/> <block><rating><stars>4</stars><reviews>21</reviews></rating></block> <block class=&quot;title&quot;><strong>Bangkok Thai</strong></block> <block><span class=&quot;description&quot;>725 Clinton Ave, Berkeley, CA 94704</span></block> <block class=&quot;subtext&quot;>Every curry paste is made from scratch, say Bangkok Thai's owners: Peels are extracted from expensive fresh kaffir limes, which are blended in secret combination with... <inline-trigger><label>read more...</label><load event=&quot;activate&quot; resource=&quot;#&quot;/></inline-trigger></block> </layout-items> </placard> </module> </content> <page-footer><block class=&quot;small&quot; halign=&quot;right&quot;>Copyright Shmarranabab inc.</block></page-footer> </page>

To control caching, use the following standard HTTP headers when serving pages: Cache-Control, ETag, and If-None-Match. Only these headers affect caching
