The Push-Mi, Pull-Yu event-notification kernel for enhanced publish/subscribe

The Push-Mi, Pull-Yu event-notification kernel was developed for enhanced publish/subscribe. Push-Mi, Pull-Yu comprises separate components for event detection, publication assembly, publication and subscription matching, subscriber notification, and publication propagation. The system also includes several repositories to store event, subscriber, publisher, and publication type information. It also contains several staging areas that manage system input and output and keep track of partially matched subscriptions for composite event detection and event correlation.
