IdAS 1.0 Package
Revision as of 21:01, 7 February 2008 by Paul.socialphysics.org (Talk | contribs)
The Identity Attribute Service (IdAS) component provides a virtualized, unified view and a common means of access to identity information from multiple heterogeneous data sources. IdAS is an extensible framework based on the Higgins Global Graph that represents identities (Nodes]) and their Attributes in a Context. Data sources are adapted to the IdAS framework via plug-ins called Context Providers.
The IdAS framework is comprised of three sub-components (see Components page for more details):
- IdAS API
- Allows a consumer to perform access and update operations (as allowed) on elements of the Higgins Global Graph. Specifically, the consumer can obtain an object which represents a Context, can read and change Node within that Context, and can read and change attributes on those subjects.
- IdAS SPI
- Is used by parties who wish to write Context Providers for IdAS. The IdAS API is only a set of interfaces which must be implemented by Context Providers. A Context Provider consists of the implementations of IdAS SPI interfaces which allow a consumer to access some specific type of identity store.
- IdAS Registry
- Is responsible for resolving a ContextIdDatatype to all the information needed to obtain a suitable Context Provider, and to further instantiate the Context identified by the ContextId. IdAS Registry can keep an internal list of Context Providers and ContextIds, or it can use external mechanisms such as XRI Resolution.
- IdAS Common
- A set of common, useful utility methods.
Plan
This section relates to the union of the IdAS API, SPI, Common and Registry sub-components.
