What Abstractions Enable Event Processing? The afore-mentioned points can best be
addressed by The content-based publish/subscribe model Realized by content-based message routing
Events are conveyed as publications.
Event listening, filtering and correlating is based on content-based subscriptions managed by the pub/sub system.
