[digiKam-users] list all utilized Metadata over a selected set of selected images

[Gerhard]

Hi,

my collection contains images from various sources, and thus diffent
metadata items  utilized. I want to collect all utilized items, and set
all of them as view preset. So i'm  looking for a way to find out all of
them.  Can this be done inside digKam, or would i need to find a way to
parse images/sidecars by some other tool?

Cheers, Gerhard
