The Liberty ID-FF Convergence

Up to version 1.1, the Liberty ID-FF was developed using the SAML 1.0 specification. The Liberty ID-FF 1.2 was then developed using the SAML 1.1 specification. Following the release of version 1.2, the Liberty ID-FF was reintroduced into the SAML 2.0 specification. Additionally, SAML 2.0 adds components of the Shibboleth initiative. Going forward, SAML 2.0 will be the basis on which the Liberty Alliance Project builds additional federated identity applications (such as web service-enabled permissions-based attribute sharing). As such, SAML 2.0 is a critical step towards full convergence of federated identity standards. The following diagram illustrates the convergence history of SAML and the Liberty ID-FF.
