No problem for the sound, Daniel, especially when it come from a
But my purpose of my mail is... witch IPTC tags is need to use to store
digiKam tags and rating informations !
My proposal is just a first approach. If you have already used a photo
managment software witch use IPTC with the same digiKam functionnalities
(under MAC or Win32), i would a feedback about that, to give a compatibily.
IPTC tas descriptions are very generic (take a look in IPTC spec. for
example), because IPTC isn't dedicaced to photograph only. We need to choose
the right tags to store digiKam information
Writting digiKam tags to IPTC ins't really difficult with Exiv2 library. Today
i have implemented Rating to IPTC implementation (to svn). Still digiKam tags
