Read image XMP data in Python

Question

Can I use PIL, like in this example?

I only need to read the data, and I\'m looking for the easiest simplest way to do it (I can\'t install

reading raw file metadata does not work

This thread started 8 years ago and things might have evolved. I am not very deep in xmp and xml and I think I do not want to be. What I need to do though is to read and write metadata to image files (keywords ratings and the like).

So python-xmp-toolkit seems to be the best way to do that. It is the python layer based on Exempi as far as I understood.

So everything goes fine for jpg files. I get a dict with the keys:

http://ns.adobe.com/xap/1.0/mm/

http://ns.adobe.com/xap/1.0/

http://purl.org/dc/elements/1.1/

http://ns.adobe.com/camera-raw-settings/1.0/

http://ns.adobe.com/lightroom/1.0/

http://ns.adobe.com/tiff/1.0/

http://ns.adobe.com/exif/1.0/

with those I can access any metadata I wish.

But when I would like to do the same thing on a raw or sidecar file eg. .raf or .xmp the dict is empty. What am I doing wrong?

from libxmp.utils import file_to_dict
xmpPath = '/Users/me/image0001.jpg'

xmpDict = file_to_dict(xmpPath)
for key in xmpDict.keys():
    print(key)
