The Higgins data model provides a common representation for identity, profile and relationship data to enable interoperability and data portability across heterogeneous sites and systems.
The Higgins framework is has three layers:
- The upper layer
- Provides end-user applications called "Identity Selectors" that manage I-Cards and present end-users with a visual metaphor for the Digital Identities and their component Claims.
- The middle layer
- Provides web services for Identity Providers and Relying Parties
- The lower (data) layer
- This layer is based on a data model abstraction includes data stores called Contexts, the Entitiess within them, the Attributes on each Entity, and the links (called Relations) between them. This is the "pure" data layer. The abstract data model is realized as concrete data by the Identity Attribute Service (IdAS) and supporting Context Providers.
The Higgins Data Model is described in two sections:
- Higgins Global Graph Describes the part of the model used by the "lower" layer.
- Tokens, Claims and I-Cards describes additional concepts used in the upper and middle layers including Digital Identity, Claim, I-Card and others.
See Data Model Background for more information about the motivations for and design goals behind the model.
