The feature

Hi, is there any way to import photos with external tags created in Darktable into Immich while preserving the tag grouping structure?
Darktable uses the level_1|level_2 format for grouping tags, whereas Immich seems to use the level_1/level_2 format.

Have you tried it? Immich already handles darktable's format.

Yes, I tried it, and the tags were successfully imported, but the groups were split into multiple individual tags. For example, from the tag level_1|level_2, I ended up with two separate tags: level_1 and level_2. I will try again.
