With the prospective to give to the audience an harmonized unique graphic view of the most important open identity standard technologies, I've created a Cube.
As you can see in the above cube picture, each front-face have a corresponding back-face (i.e. OpenID->OAuth, SAML->Id-WSF, InfoCard->WS-\*) or if you rotate (imagine) the cube you can have different prospectives (inter-enterprise/SaaS, consumer, ect.). There are also some other interesting aspects as adjacent property, related to create an hybrid system (See bootstrapping the Identity metasystem), that is, combining or chaining systems and enabling transaction between them (i.e SAML -> OpenID, InfoCard -> ID-WSF, SAML->OAuth). Is this a magic cube of Identity? Comment it ;)
These models/systems could open interesting opportunity for the Italian National Centre for IT in Public Administration (CNIPA) which is involved in defining a National Federated Identity Management system based on SAML2.0, implementing a user-centric mechanism used to authorize and control the access to application services over SPCoop (Public Cooperative System).
