Change the datatypes of yard number and call signEdit

yard number and call sign are currently locked to the "string" type, but they are in fact external identifiers by definition. So I think it would be prudent to set these two properties to "external identifier". De728631 (talk) 15:42, 27 April 2019 (UTC)

@De728631: (I've moved your section, since it wasn't a property proposal.) I don't think this would work, because if you were to use the external ID datatype you would have to link all of the statements to a particular website which happens to use the exact identifiers in its URLs (e.g. Unless there's an official website that does that I don't think it would be appropriate to change the datatypes. (Changing the datatypes would also necessitate deletion of the original properties, since you can't actually change a property's datatype.) Jc86035 (talk) 16:45, 8 July 2019 (UTC)
you can't actually change a property's datatype - not true. --Matěj Suchánek (talk) 17:57, 8 July 2019 (UTC)
Ok, thank you for your input. I wasn't aware that the "Identifier" is always connected to some database website. De728631 (talk) 21:43, 8 July 2019 (UTC)
@Matěj Suchánek: Thanks for the correction. Is this not the case? I was under the impression that properties always had to be re-created if the datatype was to be changed. Jc86035 (talk) 12:02, 10 July 2019 (UTC)
The impression is and isn't wrong (cf. Wikidata:Identifier migration). As far as I know from the developers (and it makes sense), it's possible to switch between datatypes which internally hold the same type of value. You can look up this information on Special:ListDatatypes ("The value type for this data type is ..."). --Matěj Suchánek (talk) 12:27, 10 July 2019 (UTC)

External identifiersEdit

Hi All,

I wrote a proposal about expanding the statements regarding external identifiers, please have a look and add your opinions:,_best_practice --Adam Harangozó (talk) 20:50, 3 November 2019 (UTC)
