Sync metadata (star ratings, colour labels, tags) between Adobe lightroom and darktable

After a shoot, I use the colour, star, and tag metadata to sort photos. I then edit in either lightroom or darktable, depending on the photo (they both have their strengths for different things). Is it at all possible to sync the star ratings etc both ways?

I know darktable imports that stuff from lightroom on first import, that’s a start but not quite what i’m looking for.

I get the feeling this might be possible with a darktable lua script?

It should be possible to do through XMP files.

Not sure how it would work on the LR side, but in DT set it to write XMPs on edit and to look for changes on start up.

It likely involves changing the xmp naming scheme (dt approach) so LR could read the tags. I’m not sure if it is worth the trouble.

Ah yes, forgot about the different naming scheme.

Color labels are not standard metadata so you’d need a script to sync between the two apps.

Seems like an exercise in futility to be honest.
