Hi! A while ago I posted some information about how to add AppStream data to KDE projects, in order to make the projects visible in software-centers like Apper, Muon and GNOME-Software. I also compiled AppStream data for most KDE projects from the existing information we have on the web[1]. So far, AppStream metadata adoption has been good in KDE, but we can certainly do better! Fedora is already pulling in additional metadata from external sources (giving it an impressive 42% metadata coverage for KDE apps now), which is less than ideal (e.g. the data can't be translated - but it's still better than no data). Because adding the metadata is one of these very small things one easily forgets, and because we expect project maintainers to do additional work by looking at the XML spec and thinking about a description for their project, I plan to add AppStream data to the remaining KDE projects now. This will save the project maintainers from doing extra work to get their application visible with rich metadata in software centers. If you don't want me to add stuff to your repository, please drop me a note (private email) within the next week. We are speaking of a small bit of XML, which is placed in CMAKE_INSTALL_METAINFODIR (/usr/share/appdata) - so this is not a change which could break anything (in case you still don't like it, you can always git-revert, but in that case, it might happen that distributors make up their own metadata file).
For more information about this data in KDE, take a look at this blog post: http://blog.tenstral.net/2014/05/translated-appstream-metadata-for-kde.html If you want to create your own data, you are lucky: We just updated the quickstart guide, which describes how to write the data and provides some hints on how to create better data: http://www.freedesktop.org/software/appstream/docs/chap-Quickstart.html#sect-Quickstart-DesktopApps If you have any further questions/suggestions etc., let me know! Cheers, Matthias P.S: There is now a libAppstreamQt[2] available as well (used by muon so far) for very simple access to AppStream data - if your application could benefit from the data, you might want to try it!
