I've had similiar experiences when trying to use the same tag structure
in different programs. I had thought that if the tags are stored in the
xmp sidecar files it would be easy to have tag trees synchronized over
different porgramms, computers or even OS.  So I intuitively also
believed that data stored in sidecar files are synchronized to data
stored in tha database and vice versa. Be it automatically or on demand.
However this does not work (for me at least, might be I'm doing
something wrong). Not even with between two installations of digikam.

DK is one of the mightiest image management tool. And I really like it a
lot. But this issue is really a blocker for me.

It would be great to know if this is a problem of philosophy or of
technology. IE is the behaviour intended to be like this (and will not
change) or are there technical limitations, problems, etc keeping DK
from synchronizing metadata between sidecar files and database?
