Ahaha. welcome in interroperability world with closed source program.

I implemented LR tags support (reading and writing). The proof :

READ :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/libs/dmetadata/dmetadata.cpp#L1138

WRITE :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/libs/dmetadata/dmetadata.cpp#L1208

If LR has changed something in XMP tags naming, well, how to know...
It's closed source after all...
