SEWA looks like a great concept for crowd-sourcing information, especially in the event that our Sona systems, including redundant ones, should crash or fail. The people will hopefully be mobilized to harness that mobile technology to communicate to each other for the benefit of the city.
Mobile-based Early Warning of Floods looks like a powerful tool that we could leverage for our broadcast system. Obtaining access to real-time and predictive weather data is a challenge in most places around the world, so we'd be looking to partner with good quality sources and a delivery mechanism for informing the public.
Concerning the quality of information, we will build in a quality review into the process before making it available to our customers. We will put out calls for information areas that need to be developed and NGOs will be allowed to curate the content and submit it to us. We will review the content and if it meets our quality bar the information will be published on our platform. Preventative and awareness information deals with certainty and a high degree of contextual data, so it must be structured clearly. By partnering with educators and health providers we can vet the information before our customers gain access to it. We don't want to lose the trust of the people, so we will be especially careful around the broadcast information. We will partner with key government agencies and NGOs for this type of information.
In the event of a system crash, should the primary redundant system(s) fail, then the secondary system would be setup in such a way that it's hosted outside of our normal facilities. We would likely leverage a telco, setup on larger infrastructure, to support the broadcast communication and communicate out to the user base about when the passive services would be restored. In all likelihood, losing all backup systems would be a very infrequent occurrence, and the main idea of Sona is to enable people with information which they can use to prepare themselves for the future.
