number of records (P4876)

I changed the number of records (P4876) from 67 to 66, because the non-working identifiers are two (6 and 64). --Horcrux (talk) 07:05, 19 April 2021 (UTC)

URLs have changed

The URLs are changed and links are now broken. I fear also IDs havechanged.

Le search formatter URL (P4354) is not anymore https://www.anpi.it/luoghi-di-memoria/ but https://www.anpi.it/luoghi-di-memoria-e-resistenza.

Taking a random item, the ID for Monument Ossuary of the fallen Partisans (Q48810467) is not anymore 47 ( https://www.anpi.it/luoghi-di-memoria/47 ) but 91626 ( https://www.anpi.it/node/91626 ) Danysan1 (talk) 14:46, 18 April 2023 (UTC)

@Horcrux: as proponent. I think you are right; I think the best solution would probably be manually correcting all the values, since the property currently has less than 100 uses; but other options may be considered. --Epìdosis 19:58, 18 April 2023 (UTC)

Thank you for having pointed this out. This is strange, because for ANPI person numeric ID (P9267) they made a redirect from the old URL to the new one (for instance, https://www.anpi.it/donne-e-uomini/2476 currently redirects to https://www.anpi.it/node/106176). I'm trying to contact the webmaster. In the meanwhile, I changed the formatter URL to https://web.archive.org/web/https://www.anpi.it/luoghi-di-memoria/$1, in order to make the content accessible again.

In any case, I would not correct the current values for this property: we probably need a new property that merges P9449 and P9267, since they now share the same URL prefix. --Horcrux (talk) 07:36, 19 April 2023 (UTC)

Thanks @Horcrux:; let's wait if they answer your emails; a new property for all new values, keeping P9449 and P9267 for historical purposes, is probably the best solution. --Epìdosis 07:40, 19 April 2023 (UTC)

@Danysan1, Epìdosis: They incredibly fixed the bug and answered me in about ten hours :-) --Horcrux (talk) 20:40, 19 April 2023 (UTC)
