An Event Registry Service is used to facilitate the development
of event notification systems that can notify a set of subscribers
about the occurrence of a specific event.
This service operates on the following three kinds of registries:
When users subscribe to a specific set of events using this
service, they are added to an Event
Subscription Registry. The service can also maintain types
of events (defined in the Event
Type Registry), and register the occurance of specific
events (in an Event
Instance Registry).
Event notification systems can be developed that will monitor
the contents of an Event
Instance Registry, and notify clients that have subscribed
to that particular type of event using contact information
stored in an Event
Subscription Registry.
