nixos-appstream-data VS nix-software-center

I don't plan on it at this moment, however, if someone finishes the packagekit backend for Nix, the appstream data I'm working on collecting would work to display icons and screenshots. Also if someone who knew qt/kirigami development wanted to make something similar to nix-software-center, the backend tool that reads and modifies configuration values is a separate project: nix-editor, and I would be willing to help with any issues that arose from that.

Currently, metadata is stored on my NixOS Appstream data repo

That makes sense, too. You might also be interested in nix software center.

you can use nix-software-center by vlinkz
