We proposed a scheme for an installed Web apps to register for URL handling behavior through the web application manifest, such that it may launched when matching URL links are activated. Native applications today on many operating systems (Windows, Android, iOS, MacOS) are able to register for URL handling. This work targets the Web Application Manifest specification (https://www.w3.org/TR/appmanifest/<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.w3.org%2FTR%2Fappmanifest%2F&data=04%7C01%7Cluigonza%40microsoft.com%7C0a7789fb25124dc7046108d941997961%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637612949711272971%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=DZgVX1YB4CQ2G%2BUlN%2Flr4ATGfSyOdBYOIwHNX69Co6w%3D&reserved=0>). Changes will include recognizing a "url_handlers" field in the manifest to register for URL handling, as well as adding a "Web App Origin Association" supplement to the spec. that specifies how registered origins are validated. Status Web app URL handling is being implemented in the Chromium browser as an experimental feature.
