Goals for v1

For the first version, we aim to standardize the following:

• A link relationship for manifests (<link rel="manifest" href="...">).
• The well-known URI for a manifest resource (/.well-known/manifest.json if no link relationship).
• Application's name and icons and how they interact with HTML equivalents.
• Display mode hinting (browser, minimal-ui, standalone, fullscreen).
• Screen orientation hinting.
• Start URL.

Goals for v2 and beyond

• A way of for scripts to check if the application was launched from a bookmark (i.e., similar to Safari's navigator.standalone).
• Media query based orientation and display mode.
• CSS media features for display modes - @media all and (display-mode: browser).
• Define how navigation works.
• URL scope for a web application (i.e., "foo.com/bar/*" is my app, other stuff opens in default browser).
• Service Worker integration.
• CSP policy tightening.
• Updatable manifests - update the installed application to enable new capabilities after install.
• Clarify how this works with HTTP's Link header.
• Inline manifests (or HTML meta equivs?).
• Splash screens (or prerendered pages that serve as one?).
• Make installable apps sharable.
