Pascal,

Thank you. I ran exiv2 as suggested on a jpeg output file, and most of 
the sidecar data were there.
Thank you for answering a newby question.
Kind regards,
Willem

It's the only solution. Modifying original RAW files is borderline insane.

The sidecars apply to your RAW originals, not your JPEGs.

Most of the original image EXIF including most of the sidecar is
however embedded into the output files.

Try:
# exiv2 -pa darktable_exported.jpg

This should already be the case. Most of the metadata is incorporated
into EXIF as far as possible (and yes EXIF is limiting in this
regard). The rest is set in the XMP attached to the exported files
(which is basically just the sidecar embedded).

Darktable is intended as one stop image management solution, so
Digikam compatibility (by itself) isn't really a concern.

That said, if we are violating some standard, we'd certainly look into
it, but I don't think there is any reason to think that's the case.
