The Common Alerting Protocol (CAP) is a simple, standard format for exchanging all-hazard emergency alerts and public warnings over all kinds of networks. CAP allows a consistent warning message to be disseminated simultaneously over many different warning systems, thus increasing warning effectiveness while simplifying the warning task.CAP also facilitates the detection of emerging patterns in local warnings of various kinds, such as undetected hazard or hostile acts. And CAP provides a template for effective warning messages based on best practices identified in academic research and real-world experience.
