As part of its plan to promote identity management across multiple platforms, Microsoft is funding several new projects to develop open source versions of its digital-identity technology for information cards.

The company also Wednesday released another specification for building a Web-based architecture to support centralized digital identity, called the Identity Metasystem, under its Open Specification Promise (OSP) program. OSP, launched last September, gives developer access to Web services protocols Microsoft has developed over the years without the need for a license or fear of legal action from the vendor.

Microsoft's Identity Selector Interoperability Profile (ISIP), which helps identity providers share digital identity information, is now available under OSP, said Jean Paoli, general manager for interoperability and XML architecture at Microsoft. Using digital-identity information across multiple networks will allow Web users to sign on once across different Web sites, and also allow those providing identity verification and management to share information safely across systems and sites.

ISIP includes several of Microsoft's XML-based Web services specifications, such as Web Services-Trust and Web Services-Security Policy, which together offer a standard framework to protect user identities when they are being passed between different systems. This happens in online transactions or other scenarios where user information is shared over a network.

The new open source projects will develop information cards implementations for Java for Sun Java System Web Server, Apache Tomcat or IBM's WebSphere Application Server; the Ruby on Rails rich Internet application framework; and PHP for the Apache Web Server. SourceForge.net and RubyForge.org are hosting the projects, and they also will be available on Microsoft's CodePlex site, which hosts open source projects.

Microsoft also is funding another project to implement a library for the C programming languages that can be used by any Web site or service to leverage information cards on Windows using Microsoft's Visual Studio developer toolkit.
