Hello, you add years of birth for several biographies (Q3131628, Q523844, Q1450815) when there is already a date of birth with a reference, why double it? Bien cdlt

P.S. : FYI, with some records on my watchlist, I moved the Open Library identifier to the specific date.

See the other topic... I was adding Open Library as a reference, but QS decided to add the date a second time, then fail at adding the actual reference.

I found the solution by searching. When we add a year with an identifier and there is already a specific date, it is necessary to put "privileged rank" to this last, so that the infoboxes work.

If you add a second birth or death date that is less precise than the previously present date, please mark it as "deprecated" (since it is less precise. Duplicate dates of birth or death get marked as problematic and cause issues for Wikipedia and other sites pulling data from the entry. For example, at Simon Dach (Q77285), there were birth and death dates giving the day, month, and year, but you added a second data entry for just the year. I have marked your additions as deprecated, and you should do this if you are duplicating dates with less precision.

For entries where there is already a date exactly matching what you are adding, you should simply add the reference, not duplicate the date. You did this at Richard Josiah Hinton (Q61643575) and this creates a problem of duplicate values. Simply add the reference rather than duplicating the data value.

I would also point out that using OpenLibrary as a reference adds nothing. Most of the dates of birth and death at OpenLibrary were added anonymously without any source for the information, so it is not a valuable or reliable source of information.
