Hello everyone!
I have to create about 22k XMP files with a custom metadata schema:

<?xpacket end='w'?>
The tags in bold vary from file to file and folder the image is currently in. I found out how to batch create/write xmp files but I have to manually open each and every file and change the bolded values so they match the data. Is there any way to speed this process up?
1. I must have mixed up the terms, I'm pretty new to this.
I'll explain a little bit in detail:
I'm currently scanning publications, each page must have it's separate .jp2 image and this image has to have the xmp embedded into it. Each publication released in a given year has 10-40 volumes.
<rdf:li>DATE</rdf:li>
This tag must match the date the material was published. 1999, 2001 etc
<dc:format>FORMAT</dc:format>
This tag contains the data about the volume and pages in the current publication in this format:
vol 1, nr 40, 8 p
The next one will be
vol 1, nr 41, 16 p
etc
<dc:identifier>ID</dc:identifier>
This tag cointains the picture filename
id-221_vol-1_nr-40_scn-001 (scn-002 etc)
id-221_vol-1_nr-41_scn-001 (scn-002 etc)
<rdf:li>RELATION</rdf:li>
This tag contains the PDF file the picture is linked to: id-221_vol-1_nr-40.pdf
And of course every picture has it's own resolution but the exiftool reads that automatically.
So my question is: Is there any way to automate the process of updating the metadata so it corresponds to it's file and publication?
Right now I'm opening each and every file and changing these values by hand. That wouldn't be a problem but I have to do it for 22k pages.
To automate this, ExifTool must be able to read the publish date, etc from somewhere. Where does this information come from (digitally)?

The date is in the folder and file name, the pdf file is in a subfolder and the information for the dc:format field has to be done by hand because it varies.
You should be able to automate this for the date at least. For dc:format, automation won't be possible unless you create a CSV file or something like that to get the data from. You can create a blank CVS like this:
exiftool -csv -f -Format DIR > out.csv
then edit out.csv to fill in the desired Format and use it to write the Format back to the files:
exiftool -csv=out.csv DIR
If you give me specific examples about the directory and file names, I can show you how to set dc:date.
