Over the past years, @PierreSelim, @Lena and me (under the Commonists org barnstar) have worked on tools for analysing collections of media on Wikimedia Commons, program evaluation, etc.
This includes wm-metrics, which also has a Web interface on ToolLabs, its deep backend rewrite MediaCollectionDB, and SurfaceImageContentGap
See T100088, T100710 for background information.
We should discuss whether work on these tools still make sense or we should discontinue them. Cc @Abit
