• Working draft documents have been removed, to avoid confusion with the Higgins CVS repository. [These files are still attached to this page (but hidden).]
  
• See the org.eclipse.higgins.idas project in the CVS repository for the full API.  The bullets below give a quick overview of the major interfaces and methods.  (In cases where they disagree, the CVS repository takes precedence over this page.)
• 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.
  
• 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.
  
• 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.
• IDigitalSubject
• Implementation of a specific type of Digital Subject.
