How to extract the rating from a picture programatically?
I am using Capture One to process images from a Phase One camera. As part of the process, I rate the pictures from 0 to 5. I may have 10,000 images in a project: these are aerial images.
I want to extract the rating of each image programmatically using the software IDL (interactive Data Language: https://www.l3harrisgeospatial.com/docs/using_idl_home.html) which is similar to python. My question is:is the rating stored in the file itself? If so, where? If not where is it stored and how do I access it?

Have you considered syncing the metadata to sidecar files and extracting the information from there? Building a workflow around that would give you the added benefit of being able to use any application that works with XMPs, making the workflow more portable. Downside is that syncing metadata for that many images in C1 is slow.

I think you would need to put this request through the Phase One Support channel rather than Capture One if you are looking for a feature request solution.

Sebastian,
What sidecar file are you referring to? I export the files with the rating as tif files and there are no other files with a similar name created.
I have looked at the EXIF and IPTC metadata for the images and there is no reference to a "Rating". Possibly it is stored as a private tif tag but I cannot find any documentation for it.
