All About Microsoft posted a story that Microsoft has introduced a new developer concept known as Contracts with Windows 8.
Sinofsky told us workshop attendees that the closest analogy to a “contract” is a clipboard. (That got me thinking about former Microsoft Chief Software Architect Ray Ozzie’s “universal clipboard” concept — dating back to 2006. Ozzie’s universal clipboard, which he released under a Creative Commons license, was focused on connecting Web sites and desktop applications using a combination of RSS feeds, other XML data and the desktop clipboard. I don’t know how much the Windows 8 team relied on Ozzie’s vision and code, if at all.)Microsoft's new Windows 8 contracts: The debut of the developer clipboard
Microsoft officials did share more about the contracts concept during one of the Build sessions focused on the “Share” contract. The “currency” in a Share contract what’s known as a DataPackage. The data can be captured and shared in a number of different formats, including text, URI, HTML, images and other extensible formats.
