Using AppStream is a great idea, because it works across all
distributions by design. Back in ancient times, PackageKit had a
browser plugin, which allowed websites to e.g. install packages on
demand. But that was used so little, that it eventually was abandoned
(with browser vendors dropping plugin APIs playing a large part).

So, tl;dr: Use AppStream's appstream: URL handler.
