           Summary: Possibility of having the tag hierarchy also written
                    in the Xmp.MicrosoftPhoto.LastKeywordXMP field
           Product: digikam
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Tags
        AssignedTo: digikam-devel at kde.org
        ReportedBy: hugotrip at free.fr


Version:           unspecified
OS:                Linux

As my pictures library is shared over network on a windows station, Windows
Live Photo Gallery (WLPG) is used also.
When tagging in WLPG, the tag hierarchy, exported in
Xmp.MicrosoftPhoto.LastKeywordXMP is well imported by Digikam, but when tagging
in Digikam the tags hierarchy is exported in Xmp.digiKam.TagsList and in
Xmp.lr.hierarchicalSubject, and the tag leaves only are exported in
Xmp.dc.subject, but WLPG seems to be able to only import Xmp.dc.subject, and
so, I lose the hierarchy when using Digikam to tag pictures.
Therefore I'd like to have the possibility in Digikam to automatically export
the tag hierarchy of a picture in Xmp.MicrosoftPhoto.LastKeywordXMP.

Reproducible: Always




using exiv2, I've noted that the notations in Xmp.MicrosoftPhoto.LastKeywordXMP
and Xmp.digiKam.TagsList are identical, so it looks like coding this wish could
be done by simply copying the value of Xmp.digiKam.TagsList in
Xmp.MicrosoftPhoto.LastKeywordXMP.
(there may be a trick because Xmp.digiKam.TagsList is a list Seq and
Xmp.MicrosoftPhoto.LastKeywordXMP is a list Bag, but I don't think because you
copy from seq to bag)
