This API covers the operations required to allow an application (for instance a selfcare mobile app) request identity information about the individual that is making use of the functionality provided by such application (the user), or in general to allow an application to request identity related information about an individual to the system holding such identity information. This API, instead of defining new operations, relies on the use of industry standard for identity information such as OpenID Connect (http://openid.net/specs/openid-connect-core-1_0.html ) and OAuth2.0 (RFC6749).
