I've seen a several tweets and articles today stating that Apple is advocating a Javascript-based Model View Controller framework for web development called SproutCore. Reports indicate that Apple based the MobileMe web application announced at WWDC on SproutCore and provided details on the framework in sessions at the Apple World Wide Developer Conference last week in San Francisco.

AppleInsider has a very good article called Apple's open secret: SproutCore is Cocoa for the Web that goes into some details about why Apple is so interested in SproutCore and why Apple may be switching some of the animation and special effects on its website to SproutCore from other frameworks like Prototype and Scriptaculous.

That article lead me to SproutCore - Feature Rich Javascript Framework, which says that SproutCore is a JavaScript implementation of the Cocoa framework commonly used in MacOS X application development.

This article in turn pointed to Cocoa for Windows + Flash Killer = SproutCore from RoughlyDrafted Magazine which explains why Apple would prefer to use HTML, Javascript, and CSS rather than Flash to implement rich internet applications on the web.

It's pretty clear from this article that Apple not only wants to avoid becoming dependent upon Flash or Silverlight so that it can control its own destiny, but that it wants to use a Javascript framework like SproutCore to build web applications that usurp some of the power of the Windows platform by making Windows less and less necessary. Check out some of the comments to this article if you want to really get into why Apple is making the strategic architecture bets that it is on the future of MacOS X.
