I don't want to manually patch it into the openSUSE rpm package. This is something you should maintain for every distribution.
This task depends upon

Updated the file with slightly more suitable screenshots.

Some dude via mail:

We've been busy building an awesome software center, and we've been adding more and more metadata fields that upstream authors can set. The software center is now being used in Fedora, Opensuse, Ubuntu, Debian and Arch, with many millions of happy users.

Some of the newest features include a way to make it easy for translators to contribute new translations of your applications by specifying a URL in the openttd.appdata.xml AppData file that tells them where to start looking. This can be specified by adding:

<url type="translate">http://the-web-site-with-translation-instructions/</url>

Another useful tag to add is to tell end-users where to donate, for instance:

<url type="donation">http://www.gnome.org/friends/</url>

If it's been some time since you updated the AppData file (and hey, you've got an app to write!) you can get add the latest metadata fields by doing `appstream-util upgrade openttd.appdata.xml` and then replacing any FIXMEs in the file with actual data. We'll be putting more functionality into the software center in the future that uses this extra data, but we need more upstream software to opt-in before we can enable features, for instance, providing a button for users to donate to specific apps.

You can also use `appstream-util validate-relax` on your AppData file to check the various fields meet our style guidelines. If you disagree with any of the validation warnings, please let me know!

Same dude via mail:

The latest feature we want to support is age classifications for games. As your application is listed in the games category we wanted to ask if you could generate some OARS metadata and add it to the openttd.appdata.xml file. It's really as simple as visiting http://apps-xdgapp.rhcloud.com/oars then answering about 20 questions with multiple choice answers, then pasting the output inside the <component> tag.

Using the <content_rating> tag means we can show your game with an appropriate age rating depending on the country of the end user. If you have any comments about the questions on the OARS page please do let me know.

Which package managers should we support today? Which in 5 years?
Comment by Matthias Mailänder (Mailaender) - Monday, 13 March 2017, 18:23 GMT
The appdata.xml file is independent from the package manager used.

For the Open Age Ratings Service you can take https://github.com/OpenRA/OpenRA/pull/12044 for reference where I did this for OpenRA. I am not sure where this is exposed though.

And what needs to happen with the file? Does it need to go somewhere specific? Is it just part of the source or does it need to be installed?
Comment by Matthias Mailänder (Mailaender) - Wednesday, 15 March 2017, 19:10 GMT
It needs to go to /usr/share/appdata

See https://build.opensuse.org/request/show/416036 for an integration test of this file.

It's great you're adding meta-information to all applications for your users. It is even more great that this is done across distributions.
However, you're only doing Linux, not windows, not osx, not <insert random non-linux os here>.

So why do you want application developers to make only your users happy?

The better solution would be imho to make a cross-Linux-distribution repo with this stuff for all applications that your OS(es) support. You can add whatever you want in whatever speed you want. Frankly, we have more than enough problems with just the application, we don't need more work.

Copying it into your repository shouldn't be that much of an effort. If your attitude would be more friendly and your source code repository more accessible, I might have even setup a patch for the Makefile install rules or l10n support.
Comment by Peter Nelson (peter1138) - Sunday, 10 September 2017, 22:46 GMT
I guess it would go in the os/rpm/ directory and then however that stuff works would put the file into the package that gets built. None of my non-RPM systems have a /usr/share/appdata to care about.

Ubuntu 16.04 should come with GNOME Software which also displays these by default.
