What are some applications that use XRI?
I-name and I-number registry services for privacy-protected digital addressing use XRI. The iSSO protocol under development at XDI.org uses XRI resolution to bootstrap usage of SAML 2.0 authentication assertions for cross-domain single sign-on. The i-tag initiative for intelligent, identity-enabled tagging of structured content in the blogging and RSS syndication industries uses XRI. XRIs also form the basis for the XDI trusted data sharing protocol under development by the OASIS XDI Technical Committee (http://www.oasis-open.org/committees/xdi). See the XRI TC home page (http://www.oasis-open.org/committees/xri) for additional links.
