    Notes


    Known VIAF/GND problems

    VIAF is helpful but also often incorrect, outdated, and is mixing two identifier systems that in some cases produce dead links.

    1. Johannes Fabian (Q15641418), VIAF 91414487 merged in January 2014 three GNDs, only one was correct:
      1. GND 107342049: Fabian, Johannes R., undifferentiated
      2. GND 122878310: Fabian, Johannes (* 1937), Amerikan. Anthropologe
      3. GND 172084180: Fabian, Johannes R., Dipl.-Ing.
        • Update: now both Wikidata and VIAF have only one GND
    2. VIAF changes numbers with dashes: Instituto Brasileiro de Geografia e Estatística (Q268072).
      1. GND 1026669-0 (correct)
      2. VIAF-GND 004164695 ("404 Not Found")
    3. Same name + same year of birth = different person
      1. In some cases VIAF merges two persons because only one of them has a GND
      2. Please use: GND = "no value" (for the person without a GND) [1]
      3. For items often confused use: different from (P1889)
    4. For unknown reasons VIAF is not importing all GND ids
      1. Samuel Ramos (Q7412445) = GND 1022446479 (created 16-05-12)
      2. June 2015: 3 years later the GND id still not harvested by VIAF
        • DNB and VIAF have been made aware of the problem, there might have been a harvesting glitch during the first weeks of the GND going live in April 2012: GND records which never have been touched since then are still unknown to VIAF (as an estimate about 15.000 GND records for persons created in early summer 2012 are not represented in VIAF). [7. Jun. 2015‎ Gymel]
        • Update: GND 1022446479 added to VIAF:59099151 on 2015-07-12.
    5. In some cases VIAF clusters get deleted instead of merged
      1. Åke Blomström (Q270863): VIAF 228866914; taken care by KrBot
    6. In rare cases VIAF clusters are reused for a different item
      1. William of Ockham (Q43936): VIAF:41835567 in 2015
        1. Lorenzo Traversagni (Q18674108): VIAF:41835567 in 2016
        2. William of Ockham (Q43936): VIAF:262145669298005170004 (created 2016-02-28)
      2. Drew Fudenberg (Q1258707): till 2016-09-25 VIAF:59183378 (now: "First National Bank of Lynn")
    7. In the case a conflated VIAF cluster was used for creating an item, see Help:Conflation of two people (Wikidata:VIAF/cluster)
    Format “(|1[012]?\d{7}[0-9X]|[47]\d{6}-\d|[1-9]\d{0,7}-[0-9X]|3\d{7}[0-9X]): value must be formatted using this pattern (PCRE syntax). (Help)

    DiscussionEdit

    Second half of 2021Edit

    @Emu, Kolja21: The second half of 2021 is starting, let's make a new point of the situation for GND and DtBio. I just add here the first points:

    • numbers: as of now 1'252'200 items having P227 as main statement and 627'074 items having P7902 as main statement
    • backlog of 2020 import: still 1138 items from 2020 import having the same VIAF as another item (https://w.wiki/3VzL)
    • backlog of 30/6/2021 import: 4224 items having substantially no data (https://w.wiki/3ZrH), @Bargioni: has accepted enriching them from GND in the next weeks

    I am not opposed in principle to new imports, but I think it is better to delay their discussion after cleaning the backlog from 2020 import. If you have any idea about the current situation, problems to be solved and perspectives for the next months, we can discuss them here with the greatest pleasure for us all! Good evening, --Epìdosis 18:49, 30 June 2021 (UTC)

    No. 3: Thanks @Bargioni. Importing data from GND will bring us a great step forward. No. 2 is tricky since VIAF clusters are unstable. Same problem with BBLD (Property talk:P2580). The blocked user seems to be the same who has access to Baltisches biografisches Lexikon digital (Q18616550). He is doing mainly copy & paste edits:
    The BBLD IDs have changed two or three times (own IDs, tests with ISNI, now mainly GND). We should keep an eye on these items. --Kolja21 (talk) 19:19, 30 June 2021 (UTC)
    About the backlog: Items like Ferenc Karacs (Q1104400) [2] and Marko Martinović (Q4282609) [3] are imports from Biographisches Lexikon des Kaiserthums Oesterreich (Q665807). Plus there are thousands Mathematics Genealogy Project ID (P549) imports with information about an university degree. These items have to be further individualized and merged if the person is known in Wikipedia. Those who did their doctorate in Germany usually have a GND. --Kolja21 (talk) 20:00, 30 June 2021 (UTC)

    backlog of 30/6/2021 import: The new BBLD importsEdit
