Related components/technologies/standards:
- Integration with Application Logs (Based on existing work)
- Performance Data
- Event subscription & publication
- WS-BaseNotification, WS-NotificationBroker, WS-Topics
- WSDM Event Format
Use Case: Client subscription to events
This use case is no longer valid for COSMOS 1.0. Archiving.
Description: This use case elaborates COSMOS efforts around WS-Notification. There will be a notification broker provided in COSMOS where notification producers and consumers can publish or subscribe to events in the context of web services.
- Client contacts the management domain
- Client queries for the notification broker associated with the management domain. Notice that an adopter can choose to replace COSMOS notification broker with a completely differently implementation that is based on WS-NotificationBroker
- Using the end point reference of the notification broker, the client queries for topics published by notification producers using WS-Resource Properties.
- Client subscribes to one or more published topics. Subscribing to a topic will cause a notification every time an event associated with the topic is raised.
