The Security Assertion Markup Language (SAML) is an XML-based federation technology used in some enterprise and academic use CASES. OpenID Connect can satisfy these same use cases but with a simpler, JSON/REST based protocol. OpenID Connect was designed to also support native APPS and mobile applications, whereas SAML was designed only for Web-based applications. SAML and OpenID Connect will likely coexist for quite some time, with each being deployed in situations where they make sense.
