Policies are rules enforced by SDL core that configure how the system can and/or will behave. For example, a policy could prohibit the use of an application (e.g. Flappy Bird) in a specific type of vehicle. In general, policies are configured by an OEM (e.g. Ford, Toyota, Suzuki) and stored in their SDL Policy Server. Once configured, all policies for a specific vehicle can be requested in the form a JSON document called a Policy Table. Policy Tables are downloaded to a vehicle's head unit where it can be enforced by SDL Core.
An example Policy Table is available in the SDL Core repository.View on GitHub.com
