The Data Model provides a common representation for identity, profile and relationship data to enable interoperability and data portability across heterogeneous sites and systems. The model is described in these sections:

Information Cards

The Information Card (aka I-Card) metaphor includes the end-user concept of I-Cards and an Identity Selector to manage them

Tokens and Claims

Higgins supports identity service concepts such as Claim, Digital Identity, Security Token and other objects used by Identity Providers, Relying Parties, Service Providers and Identity Selectors

Context Data Model

The Context Data Model 1.0 describes a data model that can makes portable and interoperable data from heterogeneous data sources such as enterprise directories, databases, communications networks, and social networks
