Data Models 1.X
Revision as of 18:29, 31 January 2008 by Paul.socialphysics.org (Talk | contribs)
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:
- Top: End-user applications (e.g. Identity Selector)
- Middle: Web services for Identity Providers and Relying Parties
- Bottom: Higgins Global Graph data abstraction layer
The Higgins Data Model is described in two sections:
- Higgins Global Graph Describes the part of the model used in the bottom layer. It includes concepts related to 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.
- Higgins Upper Model describes additional concepts used in the middle and top 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.
