Identifier for authors

The correct identifier for authors is 02-A00999999 (per [1][2]), NOT vtls009999999 which is an identifier for VTLS (Q7907618), not RERO (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)

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

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)

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

Added organization (Q43229) to allowed types

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)

Changed property constraint regex

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)

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)
