Is there a reason why this property is limited to botanists? Why not zoologists? --Slomox (talk) 09:30, 17 April 2013 (UTC)

See w:International Code of Nomenclature for algae, fungi, and plants. There are different nomenclature standards for botany and zoology. In zoology the taxon author has to be written out. 23PowerZ (talk) 20:55, 17 April 2013 (UTC)
Ah, okay, I see. The article en:Frédéric Cuvier for example has an infobox field "Author abbreviation (zoology)" with "F.Cuvier" and I was under the impression that this is the same as the abbreviations for botanists. But apparently these zoological names are not official in any way. So disregard my question. --Slomox (talk) 07:07, 18 April 2013 (UTC)
In botanic, there is a database of official abbreviations: Kew garden's IPNI.
But in Zoology, globally it is a mess (There are of course a lot of exceptions, like ornithology which is always very precise). But there are of course usual abbreviations or naming. For example, for biologists having complex names, only a part of the name is usually used. Sometimes first name's letters are added to the last name.
Example of mess: "Bonaparte" is used for Charles Lucien Bonaparte and José Bonaparte
Example of mess with a possible solution: Johann Friedrich Gmelin has for abbreviations "J.F.Gmelin" and "Gmelin". The longest abbreviation been used to avoid the confusion with other authors like Samuel Gottlieb Gmelin which has "S.G.Gmelin" and "Gmelin" for abbréviations.
On fr.wikipedia we use the terms (See here):
  • botanic official abbreviation
  • usual abbreviations outside botanic (But I agree they are not really abbreviations. Maybee we could name it usual naming)
As biologist like Carl von Linné have identified species in many groups, they can have both botanic official abbreviation and multiple usual abbreviations outside botanic (L. and Linnaeus for Linné)
So, as 23PowerZ said Property:P428 should be restricted to botanic official abbreviation.
We will see later if we want to add a property list of usual abbreviations outside botanic

Single value, formatting checkEdit

I restored both checks:

  • the single value check can help us identify issues with incorrect identifiers
  • the formatting check is more difficult to configure, but already identified malformed identifiers

That the reports include false positives isn't a reason as such not to run them. --  Docu  at 23:04, 15 May 2013 (UTC) (edited)

format constraintEdit

i changed ('t )?[A-ZldvÁÅÅÁČÉØŘŞ][ \w\.\-ąâăãäàáåčćçČčêëèéğíłñńØøöòóôřŞśșůûüùúýž']+ to ('t )?[A-ZldvÁÅÅÁČÉØŘŞ]'?[ \w\.\-ąâăãäàáåčćçČčêëèéğíłñńØøöòóôřŞśșůûüùúýž']+ to match d'Hérelle --Akkakk 11:27, 5 June 2013 (UTC)

It shouldn't be needed as the ' is already in the last part. Can't figure out however how to fix the last three though (Q2464202: Á.Löve, Q3951949: É.Desv., Q6003962: Álv.Mart.). Not sure why the current regex doesn't match them. --  Docu  at 18:12, 5 June 2013 (UTC)
they all four matches both variants in my local php version. documentation says, \w is dependent on the environment. reverted my change.--Akkakk 01:23, 6 June 2013 (UTC)
I tried a lazy fix for the last three items .. it worked :) --  Docu  at 07:22, 9 June 2013 (UTC)

replaced the old by a new pattern that is tested against en:List_of_botanists_by_author_abbreviation with reasons for some elements in the source of this page. the reason why it didn't work is that non-ascii characters are interpreted by php as multiple chars. thats why there's a + behind [A-ZÁÅČ]. --Akkakk 23:45, 22 June 2013 (UTC)

the bot that updates the reports is fixed now --Akkakk 20:40, 30 June 2013 (UTC)
Sorry but I don't understand the meaning of this regex. It excludes Westerm, Bréon, Maries, Dingler, Deleuze, M.Schultze, etc. --Valerio Bozzolan (talk) 23:21, 14 May 2017 (UTC)


According to Brya at [1] this is not unique. Sorry, if I was wrong by stating the opposite. How can it be stated that it is not unique, to avoid that others insert the same errorneous claim as I did? FreightXPress (talk) 19:54, 2 May 2015 (UTC)

Wikidata property for an identifier (Q19847637) is used for identifiers within a given "system" (a searchable website). This is quite different: this is an international standard (even if it is not universally followed). - Brya (talk) 05:37, 3 May 2015 (UTC)
