Help:P227
Help page for GND ID (P227) . This help page will be included in Property talk:P227. Please be careful editing it not to break the included page.
The Integrated Authority File (Q36578) (GND) is managed by the German National Library in cooperation with various library networks in German-speaking Europe and other partners.

Sources and abbreviations
Gadget
- To import data from the authority file you can use the gadget GND reveal. You only have to add
- importScript( 'User:Magnus Manske/gnd reveal.js' )
- to your page User:…/common.js.
Notes
- Databases to look up the GND: Online-GND (English; German) and DNB-Portal.
- For subject headings the GND uses quasi-synonym (Q2122467) what is useful for libraries but contradicts the concept of Wikidata:
- If there are duplicates: Please mark preferred GND with "preferred" rank (see Help:Ranking).
- Example Supreme Court of the Netherlands (Q133765): Q133765#P227 (former GKD = winner since it's an organisation)
- Lists of possible duplicates: Wikidata:Database reports/Identical GND ID and Property talk:P227/Duplicates
- Error reports
- Error report on German Wikipedia: de:WP:GND/F
- List of undifferentiated identifier value (Q68648103): Wikidata:WikiProject Authority control/Tn
- If a conflation is too complicated to be solved immediately: Property talk:P227/Conflation
- Wikidata:WikiProject Authority control/Error reporting procedures
- Recording companies and music publishers have yet not been imported into the GND (de:Hilfe:GND#Körperschaften). Instead of GND you can use DNB edition ID (P1292).
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VIAF is helpful but also often incorrect, outdated, and is mixing two identifier systems that in some cases produce dead links.
- Johannes Fabian (Q15641418), VIAF 91414487 merged in January 2014 three GNDs, only one was correct:
- VIAF changes numbers with dashes: Instituto Brasileiro de Geografia e Estatística (Q268072).
- Same name + same year of birth = different person
- In some cases VIAF merges two persons because only one of them has a GND
- Please use: GND = "no value" (for the person without a GND) [1]
- For items often confused use: different from (P1889)
- For unknown reasons VIAF is not importing all GND ids
- Samuel Ramos (Q7412445) = GND 1022446479 (created 16-05-12)
- 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.
- In some cases VIAF clusters get deleted instead of merged
- Åke Blomström (Q270863): VIAF 228866914; taken care by KrBot
- In rare cases VIAF clusters are reused for a different item
- William of Ockham (Q43936): VIAF:41835567 in 2015
- Lorenzo Guglielmo Traversagni (Q18674108): VIAF:41835567 in 2016
- William of Ockham (Q43936): VIAF:262145669298005170004 (created 2016-02-28)
- Drew Fudenberg (Q1258707): till 2016-09-25 VIAF:59183378 (now: "First National Bank of Lynn")
- William of Ockham (Q43936): VIAF:41835567 in 2015
- In the case a conflated VIAF cluster was used for creating an item, see Help:Conflation of two people (Wikidata:VIAF/cluster)
