Batch Metadata updating with BIMP.

[YeboiXd]

Hello. I am very new to scripting and plug-ins in general. I am trying to create a script that works with BIMP (Batch processing of GIMP) that gets the metadata from each image and updates selected fields while keeping the non-updated ones. I mainly want to update the Copyright of each of the images that are batch processed. I know I can use exiftool for this, but I am also using BIMP for more than just editing metadata and would like to only use BIMP for all these purposes. I know I need to use pdb.gimp_image_get_metadata(image) and pdb.gimp_image_set_metadata(image,data). But I just don't know how to code the script to do what I want it to do.

Thank you in advance!
