However, the raw xattrs aren’t meant to be exposed in the UI directly like that. Instead, apps should process the xattrs they understand and use them to power UI features. Some ideas of what these features might be can be found here: https://www.freedesktop.org/wiki/CommonExtendedAttributes/
But in the end, without actual implementation, they are just that. Ideas.
As I wrote before, that’s because raw xattrs aren’t meant to be exposed in the UI.
The attribute names and values are not necessarily decipherable by people. Taking one example from the freedesktop.org page I’ve previously linked: user.xdg.robots.index true. This is codified metadata, the user cannot make sense of it, and it’s not pleasing to see.
