MyAcademicID blueprint architecture is technology neutral. However we are aware that the technologies for federated identity management in use to date are largely built on SAML and OIDC. Both are well-known standards. The revision of the European Student Identifier was done in a such a way to ensure convergence between the different initiatives included under the European Student Card initiative as well as with solutions already in use among the universities. For this reason MyAcademicID consortium chose SCHAC schema as the mean to transport the ESI.
