Einzelner Wert / single value[edit]

Die Einschränkung "Einzelner Wert" sollten wir eventuell streichen. Zum einen ist es kein Fehler, wenn die numerische ID (z.B. "12293" aus der franz. Wikipedia) und die Namens-ID ("james-d-watson" aus der lateinschen WP) parallel eingetragen werden, zum anderen hat Perlentaucher für Autoren, die unter Pseudonym schreiben, in einigen Fällen auch unterschiedliche Seiten. --Kolja21 (talk) 23:19, 24 September 2013 (UTC)

"Single value" is wrong, see Ernst Jandl (Q44775) or Canan Topçu (Q84508). --Tibeton (talk) 02:13, 25 September 2013 (UTC)
Is there a possibility to divide this ID through qualifiers? P866 = a) numeric ID, b) name ID, c) pseudonym. --Kolja21 (talk) 17:52, 25 September 2013 (UTC)
Update: For case "c" there is pseudonym (P742). Any idea what property could be used to divide between numeric and name IDs? --Kolja21 (talk) 14:08, 19 January 2014 (UTC)
Text ID "ernst-jandl" is equal to numeric ID "2990". So double identifier format looks redundant. I suggest to convert all text values to numeric or visa verse. This will make data uniform and robust. This will allow to verify data using {{Constraint:Unique value}}, {{Constraint:Format}}, {{Constraint:Single value}}. This simplify data usage. — Ivan A. Krestinin (talk) 07:11, 4 November 2014 (UTC)
@Ivan A. Krestinin: Sounds reasonable. I've added "preferred value" for the numeric ID. --Kolja21 (talk) 12:50, 3 February 2015 (UTC)
I can schedule task that will convert current and future text IDs to numeric. Ok? — Ivan A. Krestinin (talk) 18:58, 3 February 2015 (UTC)
@Ivan A. Krestinin: This would be awesome. Can you also import the data from German WP (de:Vorlage:Perlentaucher = about 2.000 mixed IDs)? Unfortunately many articles still use the URL instead of the template. --Kolja21 (talk) 22:59, 3 February 2015 (UTC)
de:Vorlage:Perlentaucher states that the numeric identifiers are legacy data used until 2012. Given the care the website spends on avoiding to leak numeric identifiers they might as well being phased out. -- Gymel (talk) 07:31, 4 February 2015 (UTC)
The numbers are still in use (even if they are not shown in the URL any more), they are unique and they prove at what time an author was added to Perlentaucher. It would be a loss of information if we delete them. --Kolja21 (talk) 16:45, 4 February 2015 (UTC)
But you declared the numeric ids as "preferred" and @Ivan A. Krestinin: understood that all text URLs should be converted into the corresponding numeric value (probably by scraping it from the HTML/Javascript content of the Perlentaucher displays. We only can tell that perlentaucher.de itself "prefers" (promotes) the textual URIs and we have absolutely no information whatsoever which of the two forms will be more persistent. -- Gymel (talk) 17:37, 4 February 2015 (UTC)
@Gymel: At least you could list them as exceptions here above in the contraint violation template. Steak (talk) 20:18, 18 January 2017 (UTC)
