“Date of Publication ” prefix
No there is no such prefix as that’s not a natural attribute of a file. It’s a contextual bit of metadata for human purposes.
You’d need custom metadata to assign this value and its meaning to you.
I found the Custom Metadata section, and activated the “Date” one. But the date requires extremely specific month/day/time, not just Year:
Don’t use a Date data type unless you need a full date.
Use an Integer Number data type if you just want to input the year… or the month or day number.
