IdAS is an extensible framework that implements the [[Higgins Data Model 1.1]] (HDM). HDM represents objects (called [[Entity|Entities]]) and their [[Attribute]]s. Existing external data sources (e.g. databases, directories, etc.) are adapted to (mapped to and from) the IdAS via plug-ins called [[Context Providers]]. |

Architecture
Errata: the above diagram only shows some of the components listed below. It needs to be updated.
Components
The IdAS framework is comprised of these constituent projects (see this section) of the Components page for more details):
- Components 1.X#IdAS / Org.eclipse.higgins.idas.api
- Allows a consumer to perform access and update operations (as allowed) on elements of the data model. Specifically, the consumer can obtain an object which represents a Context, can read and change objects within that Context, and can read and change attributes on those subjects.
- Components 1.X#IdAS / Org.eclipse.higgins.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. One good way to see what is involved in building an IdAS Context Provider is to look at some of the existing Context Provider projects. It's suggested that the Org.eclipse.higgins.idas.cp.inmem project would be a good jumping-in point, as it tends to be fairly simple.
- Components 1.X#IdAS / Org.eclipse.higgins.idas.registry
- Is responsible for resolving an object identifier 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.
- Components 1.X#IdAS / Org.eclipse.higgins.idas.common
- A set of common, useful utility methods and Authentication Materials classes.
- Components 1.X#IdAS / Org.eclipse.higgins.idas.udi
- Code for supporting the resolution of Context-, Entity- and Attribute UDIs.
