Specifically wrt darktable, importing the star rating from darktable works, as 
does importing tags.

But you have to tell digikam to reread the XMP sidecars. As I usually work per 
directory, what I do is select all images in that directory (after I've made 
changes in dt) and use "Item"->"Reread metadata" (or something similar).

An alternative might be to have digikam check for changed files (can be very 
slow on startup, and I haven't checked what that does on files changed while 
digikam is running)
