SPML, SAML, and XACML
- SPML helps streamline the provisioning process.
- SAML facilitates federated identity and single sign-on. (The sequence diagram is highly simplified. The HTTP methods and redirections are not depicted. Pls refer to SAML specification for details.)
- XACML enables attribute-based access control.
These three XML-based protocols are proposed by OASIS. They are a good fit to integrate solutions across vendors or build the extranet.
