Error reports

See en:Wikipedia:VIAF/errors. Please note that VIAF retrieves Wikidata mappings periodically and rebuilds their clusters based on that (at least for items about persons). VIAF identifiers can be merged based on that or component moved to other VIAF identifiers.

Ideally this information should be moved to the item for the reference and be transcluded from there.

Error type Item(s) affected Description/Duplicates Exception Reported Resolved (also unpublished) Resolved and published Wikidata updated
Our Lady of Victories Church (Q1280925) The VIAF ID is linking to the wrong item, it's for something in a completely different country. VIAF originally had a different (probably correct) ID but changed it for some reason.
Manoel Theatre (Q576800) The item has two IDs which should be merged. The BIBSYS ID linked from 289802221 is wrong.

Complex duplicates[edit]

Andrew Gray Andy Mabbett Bamyers99 Ijon Vladimir Alexiev

Pictogram voting comment.svg Notified participants of WikiProject Biographical Identifiers Hi! I have recently added to Pericles (Q80398) many VIAF duplicate codes, but some of them were initially part of a unique cluster, then divided; they have 996 MARC tags, which (as far as I can understand) means that they shouldn't be merged. However, the only difference here is the problematic date of birth (499 BCE, 499 BCE?, 495 BCE, 495 BCE?), the person is clearly the same. I have recently encountered some similar cases ... What should I do? Is adding these codes correct? Thank you very much! --Epìdosis 18:55, 7 May 2018 (UTC)

@Epìdosis: Adding all VIAF IDs is correct. These will be reported on the constraint violations page (since an item is normally supposed to have a single VIAF ID), and hopefully one day VIAF will use this info to fix its clusters. AFAIK, when a VIAF ID is merged to another, the obsolete ID is kept for a while as a redirect, so having such IDs in Wikidata won't be fatal: but of course, at some point Wikidata should also clean them out. --Vladimir Alexiev (talk) 07:40, 8 May 2018 (UTC)

    • Not urgent, and not clear that VIAF ever will merge them, but a number of works/non-people items continue to have multiple viafs that the site seems unlikely to consider merging or redirecting soon - consider just as an e.g. viaf 181258159 ("Quartets, violins (2), viola, cello, no. 4, op. 25," by Stenhammar), 293106702 (Quatuors Cordes No 4 Op. 25 La mineur by the same- this is quartet for strings no.4 op.25 for those who don't read French), and viaf 214760611 (" Quartette‏ ‎‡m Vl 1 2‏ ‎‡m Va‏ ‎‡m Vc‏ ‎‡n op. 25‏" again by the same composer. Some of these may point to library entries of recordings and some to scores etc., may be the only difference...) Schissel (talk) 02:56, 11 May 2018 (UTC)

Sometimes there are already links in VIAF to WD, but the VIAF is missing in WD. 19:16, 31 May 2018 (UTC)
