The correct identifier for authors is 02-A00999999 (per [1][2]), NOT vtls009999999 which is an identifier for VTLS (Q7907618), not Library Network of Western Switzerland (Q3456783).

The data.rero.ch website doesn't always work, sometimes you get data, sometimes you get "No record found", but the URL is correct (proof). --Thibaut120094 (talk) 16:53, 30 June 2017 (UTC)Reply

Is it okay to delete all the vtls identifiers? --Pasleim (talk) 21:48, 19 August 2017 (UTC)Reply

Regarding the "No record found" entries, I have asked RERO directly. The answer was that there are two fields with "035 - System Control Number (R)" in the VIAF record. Take a look at this example: It contains field 035 twice. First one ist used by VIAF for link, but the correct field to use is the second one, beginning with A: "035 ‎‡a A003320701". For the very most entities both values are the same, for some they are different like in the example. In this case, the authority record has to be checked manually for the right identifier. --Sotho Tal Ker (talk) 19:41, 14 May 2018 (UTC)Reply

@Pasleim : VTLS identifiers must be converted to the 02-A or 01-R format. --Thibaut (talk) 14:25, 22 January 2020 (UTC)Reply

Since there were a lot of constraint violations due to use of this property in items about organizations, I have added organization (Q43229) to the allowed types. I do not see that RERO is limited to humans only. —MisterSynergy (talk) 11:41, 13 November 2017 (UTC)Reply

I did update the property constraint regex to be more "exact". There is either 01-R OR 02-A, neither 01-A or 02-R. Also there are always 9 digits, not any number between 0 and 9. The new regex takes both into account, and a few wrong values have been already found. --Sotho Tal Ker (talk) 22:01, 5 April 2020 (UTC)Reply

Small addendum: Some values for books or magazines do violate the new regex, but they did violate the old one aswell. I think it is better to keep those violations for now as they are currently very few and sometimes identifiers for books get added to humans, instead of the correct value. --Sotho Tal Ker (talk) 23:00, 5 April 2020 (UTC)Reply

Hello,

By working with several GLAM employees today, I found out that the Authority model on fr.wikipedia has been giving error messages for the past two years or so when a rero number is added.

Here is an example, with a Swiss historian, Q59533639. When the following rero number : A003773184 (found on this VIAF page) is added on the correct entry of Modèle:Autorité, a message signalling that the number is incorrect appears.

Is there an issue going on with the Wikidata property?

Thanks for your support!--Flor WMCH (talk) 12:55, 4 October 2021 (UTC)Reply

@Flor WMCH: The correct value is preceded by "02-", as stated in Property:P3065#P1793. Values of RERO and other VIAF members can be easily extracted from VIAF clusters through User:Bargioni/moreIdentifiers. --Epìdosis 14:58, 4 October 2021 (UTC)Reply

There has been some discussion at en:Template_talk:Authority_control#Does_RERO_need_an_update? about how this ID is not valid anymore and is being replaced with a new ID — Martin (MSGJ · talk) 08:42, 12 November 2022 (UTC)Reply

@MSGJ: I think the answer from RERO reported in the en.wikipedia discussion implies we shouldn't do anything as of now:

• "The "old" RERO authority file with identifiers in the form of "02-A000173676" is not maintained and not publicly accessible any more." = this RERO ID (obsolete) (P3065) is obsolete
• "Ideally, we should in the long term replace all RERO ID by IdRef ID: in our data as well as in Wikidata. The alignments are not finished yet, so a lot of our bibliographic data (in https://bib.rero.ch/ and in https://swisscovery.slsp.ch/) still has RERO IDs as references." = RERO will user IdRef ID (P269) and convert old IDs to IDREF/SUDOC IDs both in their database and in Wikidata
• "The identifier you proposed to put instead (https://bib.rero.ch/global/persons/2433193) is not persistent. We don't recommend to use it in Wikidata." = The IDs currently visible are not persistent, so we cannot create a new property for them

--Epìdosis 17:24, 12 November 2022 (UTC)Reply

I agree with your analysis. I have also added (obsolete) to the label of this property — Martin (MSGJ · talk) 13:21, 2 March 2023 (UTC)Reply

There is a proposal to create replacement property, please see Wikidata:Property proposal/RERO+ ID — Martin (MSGJ · talk) 10:04, 11 March 2024 (UTC)Reply

Please coders add a better 'How to'-instruction that should pop up when someone edits the rero id into a biography. It's basically easy: user has to add '02-' to the value found in the VIAF database for any persons. But up to now the script only nags afterwards that the entry without 02- is wrong. --Just N.
