These files are to set the long description for the font, and
optionally also group together font faces together into families, e.g.
so Lato Black gets paired up with Lato Hairline to form a "Lato"
super-font.

Unlike applications, the AppData for fonts only gets processed when
the metadata is created using appstream-builder. This is because for
applications there's a 1:1 relationship with .desktop files, but for
addons like fonts the relationship can be n:1 or even 1:n.

So, back to the builder. I think this is the log file for Titillium:
https://github.com/hughsie/createrepo_as_logs/blob/master/campivisivi-tit...
-- which looking at the last entry seems to suggest (no <veto> tags)
that it gets included in the metadata, at least for rawhide.

So, to check locally: vim /usr/share/app-info/xmls/fedora-21.xml.gz
seems to suggest that Titillium should be present in gnome-software.
So, running the latter in verbose mode I see;

(org.gnome.Software:9724): GsPlugin-WARNING **: failed to load cached
icon Titillium-LightItalic.png: Failed to open file
'/usr/share/app-info/icons/fedora-21/Titillium-LightItalic.png': No
such file or directory

Not good, as that file does not indeed exist, although the others
(e.g. Titillium-Black.png do). This kinda points to it being a
metadata builder issue. I'll look more at this now.

How to include fonts in Gnome Software?

[Zbigniew Jędrzejewski-Szmek]

Hi,

I was looking into what I need to do to have my fonts in displayed
in gnome-software. They all seem to fail with <veto>appdata required</veto>.

Am I correct in assuming that appdata for all (or almost all?) fonts
is generated by
https://github.com/hughsie/fedora-appstream/blob/master/appdata-tools/cre...
?
So should I add an appdata files for fonts I maintain, or is it
enough to have them in
https://github.com/hughsie/fedora-appstream/blob/master/appdata-tools/fon...

I'm going to work on documenting the font requirements today; I'll
follow up with a blog post and some new instructions :)

Okay, this is the results of a day hacking:
http://blogs.gnome.org/hughsie/2014/10/15/gnome-software-and-fonts/

Feedback very welcome. If this looks reasonable, I'll top-post again
to devel@fedora and the fonts mailing lists. Thanks.

Richard.

Hi,

maybe you could include some more information how the font appdata
files themselves should look, as opposed to the one-level-up metadata
files. E.g. I looked at the schema at http://people.freedesktop.org/~hughsient/appdata/
and they don't seem to have the string "font" in them at all.

Some more examples would be good too. Does [1] look OK?
appdata-validate complains about missing screenshots, are those necessary
for fonts' appdata?

Right, the examples I gave there are the actual files; that is the
post-0.6 AppStream version which only works with Fedora > 20.

Right, those are AppData files for applications, not MetaInfo files
for fonts and addons. When F20 is EOL I'll update that page to the new
metadata format.

Right; you need to use a metainfo file and a git version of
appstream-glib to validate those. I only wrote the code 6 hours ago :)

Not appdata.xml, but metainfo.xml -- This is the patch I want to apply for lato:
