We have a problem

@Pamputt: I was trying to add this property to Biagio Bellotti (Q3639322). Since he was both a painter and an architect, I found two identifier: the first is 25213, related to the painter (and the link generated by the property is correct – with "opere-arte"); but the second, related to the architect, is 7617 (with "architetture") and it doesn't work with this property. Does anyone have a solution?

Then, there is another problem: Arturo Tosi (Q4801807) has two identifier: 23462 and 25759 (but this is a mistake). --Yiyi .... (talk!) 17:02, 15 May 2020 (UTC)

(confl) We can either fix formatter URL (P1630) (but in such a way that would not require us to update all existing IDs) or see if there's a permanent link that bypasses the part before "autori". Probably, we can send them an email, noticing them the problem, and make them establish a redirect that does the latter. --Sannita - not just another it.wiki sysop 17:04, 15 May 2020 (UTC)

I immediately write to them. Thanks. --Yiyi .... (talk!) 17:11, 15 May 2020 (UTC)

I'm trying to face systemically this error and I prepared a google sheet with all the author taken from the official website. The sheet is here for your analysis.

Out of 9901 records I found 921 duplicate records (many times the difference is the comma separating name and surname (e.g. 800 for Ademollo Luigi and 28812 for Ademollo, Luigi). Obviously both records are related to Q3266370.

How can we proceed? Luckyz (talk) 13:52, 16 May 2020 (UTC)

Maybe I can wait their response to my email sent yesterday. Then I can send them the google sheet to see what they want to do with duplicates. --Yiyi .... (talk!) 15:33, 16 May 2020 (UTC)

I proposed the new property: LombardiaBeniCulturali architecture author ID. --Yiyi .... (talk!) 18:13, 16 May 2020 (UTC)

Multiple IDs

As representative of multiple IDs, I would like to point out Gio Ponti. He has 5 LombardiaBeniCulturali artwork author ID (P8210) and 4 LombardiaBeniCulturali architecture author ID (P8271). This is not possible to be solved by our side, I think.

@Luckyz: I confirm, only the owners of the website can solve this problem, we can only list all present IDs. --Epìdosis 18:03, 30 May 2020 (UTC)
