- The platform can use it to derive an average rating of that content, which can also be shown to users.
- An integrated recommendation engine can use it to improve the user's recommendations.
- It can be reported to the service provider.
The platform is agnostic to the rating system. It supports any numerical value (e.g. out of 5, 10, 100), but it is expected that all clients of a service provider provide values that use the same rating system.
Clients use the Content Discovery Gateway (CDG) APIs to submit ratings and the User Activity Vault (UAV) APIs to retrieve ratings.
