IPTC provides a collection of fields to tag images of artworks. While "Title" and "Creator" are working ok, Bridge does not save the "Creation date". I assume it's expecting a fully qualified date here, although IPTC clearly states that this is a string field.
That's a bug, in my opinion.

What value are your trying to enter?
Yes, Artwork Date Created is expecting a qualified date format which is what the IPTC specification calls for:
"Data type: DateTime (preferred: truncated DateTime)" XMP Date/Time format
Recognizing that this format is not always appropriate for artworks, especially pre-20th centruy or approximate dates, IPTC added Artwork Circa Date Created, which is a simple string format, to the specificatin in 2014. Unfortunatley, Bridge does not currently support Circa Date Created.

I see. That's unfortunate. Even more unfortunate is that Bridge silently removes the date without any error message or warning.

I tried "2024", "2024-01-01" and "2024-01-01 08:00". According to the spec, any of these should work.

That's Adobe's fault. They seem to only accept dd/mm/yyyy [time optional].
If you enter "2024-01-01" in the IPTC Core Date Created, you get this alert:
I think they are trying to be helpful by using a date format many people are familiar with, but they are just making things more difficult and confusing. Bridge wants you enter "1/1/2024", which is quietly converted and saved as "2024-01-01T00:00:00Z".
Adding to the mess, the date field format is not consistent across the metadata panel and File Info panels.
IPTC Core Date Created:
Date fields should accept dd/mm/yyyy or yyyy-mm-dd.
Interestingly, File Info seems to only accept yyyy-mm-dd, the opposite of the metadata panel.
The more I look at this, the worse it gets. Adobe needs to clean this up.

Thanks for looking into this. I agree that Adobe needs to clean it up, but I won't hold my breath.
