Don't lead people down a fruitless path. From their own FAQ:
>Is darktable a free Lightroom alternative?¶
Yes and no. Darktable is an alternative to Lightroom the same way any other raw editor is, since it edits raw files, but it would be a mistake to think it’s a direct replacement. Other than both being raw editors with photo library management, and looking somewhat similar, they have very little in common.
What they mean is, Darktable has very capable editing functionality, but its "library management" is such an afterthought that I would challenge whether it even deserves to be called library management. It seems to be oriented around the design philosophy that photographers should be organizing their library with CLI tools.
