SUMMARY

I am planning to use digiKam alongside darktable and appreciate how I can group files by filename such that I can manage not only the derived jpgs but also keep the xmp sidecars of corresponding raw files updated.

I have one issue though: 
In darktable I can "reject" files to sort them out. Darktable would then write a -1 rating to the sidecar xmp file, but digiKam simply shows those images as unrated just like images without a rating (or a 0 rating, I guess).

It'd be great if digiKam could adopt the -1 for something like "rejected".

OBSERVED RESULT

- Cannot assign a -1 rating
- Labels view does not permit to show/hide images with a -1 rating

EXPECTED RESULT

- Can assign a rejected/-1 rating
- Labels view has "rejected", "no rating", 1 star, 2 stars, ...

Note that Reject in digiKam use the XMP standard Red Pick Label (=1). Exmaple of JPEG file reject in digiKam :

Also in a workflow, Rating can have a different signification that rejected. You image rate because it's good for a typical work but it's rejected because it don't follow your current workflow. Both exist, else only Rating will be used.

We use Pick Labels in digiKam with a Neural Network to check aesthetic quality. Rating in used in a different space. It's explained here :

https://docs.digikam.org/en/maintenance_tools/maintenance_quality.html

In other word, if you want to see the Rejected images tagged with digiKam in DarkTable, ask to DT team to implement the PickLabel metadata, not the inverse.
