The Event-driven, or Notification-based, interaction pattern is a commonly used pattern for inter-object communications. Examples exist in many domains, for example in publish/subscribe systems provided by Message Oriented Middleware vendors, or in system and device management domains. This notification pattern is increasingly being used in a Web services context.
WS-Notification is a family of related white papers and specifications that define a standard Web services approach to notification using a topic-based publish/subscribe pattern. It includes:
- Standard message exchanges to be implemented by service providers that wish to participate in Notifications
- Standard message exchanges for a notification broker service provider
- Operational requirements expected of service providers and requestors that participate in notifications
- An XML model that describes topics.
