<keywords>

It might make sense to add keywords (aka tags) into the metadata. Previously with the 1:1 mapping of desktopfile-appdata file we were kind of able to infer relevant tags from the desktop file, but since we can now have multiple launchables that doesn't necessarily work anymore. Yet I think it would make sense to provide the ability to set keywords for a component such that it may be more easily searched for. This is pretty much 100% analogous to the Keywords entry of the desktop entry spec. This would also improve reuse of appstream data to feed into the window store metadata (which too does have a keyword system).

<keywords>
<keyword>partitioning</keyword>
<keyword lang=de>partitionierung</keyword>
</keywords>

or some such

Like https://www.freedesktop.org/software/appstream/docs/chap-CollectionData.html#tag-ct-keywords ? ;-)
I will need to check whether this works for metainfo files, but I am pretty sure it does already and just needs to be formally advertised in the specification, and appstream-compose needs to learn how to merge keywords properly (or just prefer the ones in a metainfo file if there's also some available in the desktop-entry file)

Exactly like that! :)

The Keyword tag is already be used on Flathub, so it makes sense to add it to the Appstream Standard.

This has been part of AppStream since its first draft, but just hasn't been documented for metainfo files yet.
