--- Comment #11 from David Kaspar [Dee'Kej] dkaspar@redhat.com --- (In reply to Nicolas Mailhot from comment #9)
Note however that Appstream for fonts was heavily influenced by Debian, and Debian didn't rebase its font packaging around fontconfig as Fedora did a few years ago, so a lot of the "Need to do foo in appstream because fontconfig is insufficient or fonts are broken" do not really apply for Fedora.
If the font metadata is bad for example Fedora would prefer the packager to fix the font and patch the metadata rather than hide the brokenness under an Appstream overlay (which won't exist for apps that use the fonts anyway).
I see. :) Well, I hope the AppStream and fontconfig metadata are mostly OK for the moment - at least for the urw-base35-fonts. I've spent a lot of time to get it right.
(Currently, there was a small issue with typo in AppStream metadata that has a pull-request waiting for acceptance, and small issue with Standard Symbols PS being to big when used for LGC fonts.)
