The Higgins Identity Attribute Service (IdAS) APIs are a set of interfaces which are implemented by Higgins service providers and consumed by Higgins consumers.

Overview

• IdASRegistry

  • A class that allows a Context Provider to register its ContextFactory implementations. (See IdAS Context Provider Registry for more info.)

  • Also allows ContextRefs to be registered. Registered contexts are in some sense pre-configured by one or more Context Factories, so that a user can query its metadata (including schema and policy) without creating an IContext instance.

• {@link org.eclipse.higgins.idas.IContextFactory}

  • Responsible for the creation of IContext instances that implement a specific type of Context.

  • Responsible for associating a ContextRef with the data source (or sources) encapsulated by the designated context.

• {@link org.eclipse.higgins.idas.IContext}

  • Implementation of a specific type of Context.

  • A user must "open" a context, which involves authenticating to the data source, before accessing its data.

  • Includes methods to search for Digital Subjects using context-specific attributes.

• {@link org.eclipse.higgins.idas.IDigitalSubject}

  • Implementation of a specific type of Digital Subject.
