Convert xmp-mrw-rs / picasa face-tags to xmp-mp WLPG

[yab]

I started tagging photos using WLPG a while ago and than gave picasa try. I enjoyed the facerecognition of picasa, which i feel to be better than the WLPG one. After i did some work, i realized that

- WLPG writes the face-tags to xmp-mp
- picasa reads theses tags when scanning the photos the first time but then writes to xpm-mwg-rs

I endend up with inconsistencies in face-tags loooking at WLPG and picasa. Because the work done with picasa is based on the work with WPLG and i like to work with picasa more than the other, i would like to

- delete all xmp-mp metadata
- convert xmp-mwg-rs to xmp-mp

The first step seems to be as simple as exiftool -XMP-MP:all= whatever.jpg
Doing some research for the second step, i found a solution to copy xmp-mp to xmp-mwg-rs here in this forum. But i am totally unable to understand or even more implement it "the other way round". Hopefully someone here likes to help me with this - or point me to another thread, if the solution has already been posted somewhere.

You're right, this conversion is not simple.  I could generate the necessary config file for you, but I don't have time right at the moment.  Give me a day or two and I'll see what I can do.

Hi Marino,

I have created a user-defined tag that will do this conversion for you.

See this post for details.

Hi Phil,

thank you for your excellent support!

Keep on having fun with your exiftool.


I'll try the conversion as soon as possible (right after having a new Notebook available as the old one died this morning).
