This specification defines a JSON-based manifest, which provides developers with a centralized place to put metadata associated with a web application. This includes, but is not limited to, the web application's name, links to icons, as well as the preferred URL to open when the user launches the web application. The manifest also allows developers to declare a default orientation for their web application, as well as how the application is to be displayed by the user agent (e.g. in fullscreen).
