The primary use would be api.kde.org, no? A third party looks for a solution to hardware shenanigans with Qt and finds the solid docs and the solid docs say "you may use this thingy under LGPL-2.1". If so, then surely we ought to encode all artifacts and their licensing terms. What's more,. the artifact a given class belongs to becomes relevant and I guess that's a bit tricky to sort out. > Now, I am wondering about the best approach to encode something like this into > the metainfo.yaml.

Some additional concerns that come to mind: - what 's the actual artifact name? for libraries we already have a target name so I guess we might just use that so for example that'd be KF5::Baloo. What about plugins or binaries though? - how would we make sure all artifacts are encoded? do we want to even? HS
