Notification Broker

• Notification Broker enables asynchronous communication within WSMX
  
• The broker provides following functionality
  
  • registering and storing user goal-descriptions and related results, and
    
  • notifying subscribed users of the related results.
    
• The broker currently supports the subscription to the goal-based Web Service discovery through a new entry point which fires the execution semantics responsible for
  
  • checking for the existing (and not expired) user subscriptions,
    
  • executing for each subscribed goal the discovery process, and
    
  • once new services have been matched with respect to the previous subscriptions these newly discovered services are notified to the users.
    
• The notification can employ two communication channels
  
  • Email notification, and
    
  • Web Service invocation.
