The IdASRegistry is responsible for managing context factories available in the Identity Attribute Service. Specifically, the following services are offered:

  • Initialize itself from an XRDS document. This can come from a local file, from XRI resolution or from other sources. Each service endpoint in that XRDS document describes a context factory and includes one or more <Type> elements, which describe the ContextTypes that can be opened by the context factory.
  • Discover, instantiate and configure a context factory based on a ContextId. This is the core service of IdASRegistry.
  • Discover, instantiate and configure a context factory based on a context type (a String).
  • Enumerate all registered context factories.
  • Add an already instantiated and configured context factory to the registry. This is a secondary service and in most cases should not be necessary.

The IdASRegistry has dependencies on the following projects:
