No Constraint:Single value

@Multichill: On this specific property, having multiple values seems right. I would remove the {{Constraint:Single value}}. Do you agree? --abián 10:05, 17 August 2016 (UTC)

@Abián: I don't think it's intentional, but just duplication in their database. Do you know if we have any contacts there so we can ask them what their plans are?

The Netherlands Institute for Art History (Q758610) is a good example to give, they're fixing things on a regular basis based on the constraint reports. Multichill (talk) 16:34, 17 August 2016 (UTC)

Thank you very much, Multichill. I didn't know about the Netherlands Institute for Art History (Q758610), and yes, I contacted the Biblioteca Virtual Miguel de Cervantes (Q4903493) when this property was created, so I'll contact them again and will keep you informed. Best regards, --abián 19:44, 17 August 2016 (UTC)

@Abián: Is there any update? Some identifiers are really problematic! --Epìdosis 15:49, 3 May 2017 (UTC)

@Epìdosis: I have no news, sadly. But I can ask again. I'll do it, indeed. Thanks for reminding! --abián 17:23, 3 May 2017 (UTC)

Allowed values

Hi! I've added a 6-digit value (111187 for https://data.cervantesvirtual.com/person/111187) to Q85433026, but it is not an allowed value, so a warning appears now. Could it be fixed, please? Thanks! -Aleator (talk) 15:25, 19 October 2023 (UTC)
