As the world is getting more and more connected, a requirement for a connected notification system has emerged. In this paper a universal notification system namely UNS based on stream reasoning is described that not only meets the requirement of knowledge sharing among applications but can cater to different varying and custom scenarios, is flexible and semantic web compliant. Experimentation was done considering a meeting use case in a simulated condition on real data of smart city, and the experimental results were found to be promising.
