digiKam supports XMP starting from 0.10.0 . That means that any XMP info will
be added only for photos which were tagged in 0.10.0 (or later). You could
also choose tool "Synchronise all images with database". But in your situation
I don't advise it - data written to images will be this improperly imported.

Recent SVN versions are supporting LR XMP namespace.
