According to this Ars Technica piece, Microsoft has expanded its Open Specification Promise to include its Identity Selector Interoperability Profile. Moreover, the software giant will reportedly fund four new open source projects aimed at "helping Web site owners make their sites identity aware."
The overall goal, according to Microsoft, is to improve interoperability between all three components of a Web-based identity system: the customer, the Web site owner, and the third party that can verify the customer's identity. "Our customers expect us to enable interoperability between Microsoft-based solutions, as well as across other platforms and technologies," says Microsoft's Bob Muglia. That's why the company's approach to interoperability is "customer-centric."
The open source projects will be hosted at SourceForge and RubyForge, the story says.
