SAML 1.0
The OASIS interoperability consortium today announced that its members have approved the Security Assertion Markup Language (SAML) v1.0 as an OASIS Open Standard, a status that signifies the highest level of ratification. SAML is an XML-based framework for Web services that allows the exchange of authentication and authorization information among business partners. SAML enables Web-based security interoperability functions, such as single sign-on, across sites hosted by multiple companies.
