This module is still unstable. Use with your own caution and report bugs and feature requests at Module talk:Taxobox or Wikidata talk:WikiProject_Taxonomy.

Taxobox.lua is a lua module which can automatically generate taxonomy infobox and is overwritable by classic taxobox parameters like species, unranked_ordo etc.

This module infobox is designed to be a replacement of Wikipedia's Taxobox. It provides configuration options which can control hypernym paths, show or hide certain ranks, specify content language and its configs, and make a callback and pass parameters to "classic" taxobox.

The following code

{{Taxobox
  | qid=Q464424
}}

creates the taxobox on the right hand side. The item to show is given with qid.

If you want to have this taxobox show up on each Wikidata taxon item: [1]

Internal

Method taxobox

The taxobox method provides function runs the above example. The method itself can be invoked with

{{#invoke: Taxobox
| taxobox
| qid=Q464424
| config[count]=10
}}

The number of parent taxons to show is given by config[count].

Method callback

The callback method provides function to retrieve all internal parameters and pass them to an external template. The method can be invoked with like this

{{#invoke: Taxobox
| callback
| qid=Q464424
| template=OtherTaxobox
| config[count]=10
}}

callback accepts all arguments that taxobox accepted. It also accepts an extra argument template to specify name of the template to be expanded.

I18n

Change the i18n messages in Module:I18n/taxobox. I18n also specifys some format strings which can be use to customize the infobox output of certain language.

message description example(s)
rank-format Format of instances of
  •  

427626

, or

  •  

713623

. Will be passed into 2 named arguments when rendering ranks:

{link}
Wiki link to the rank
{label}
Display title of the rank
  • "[[{link}|{label}]]": display name and give a hyperlink to the rank, or
  • "{label}" only display name of the rank

rank-format-<latinrank> This argument is similar to rank-format but can be use to specify the format of certain rank. The "<latinrank>" is a latin name, can be a instance of

  •  

427626

, or

  •  

713623

. For example "rank-format-cladus" for

  •  

713623

. It accepts same 2 named arguments like rank-format

  • "": don't display anything at this rank. Can be used to hide the rank name when the taxon is a clade
  • "<i>(clade)</i>": use italic style
  • "[[{link}|<span style=\"color:gray\">{label}</span>]]": use link and change color

item-format-current-with-vernacular-name Format of instances of

  •  

16521

or 
  •  

310890

. current means either the item is the main taxon (specified by module argument qid), or the item and all taxa between the item and main taxon (if any) are all

  •  

310890

. with-vernacular-name means the item's 1843 or label exists and is different from 225.

4 named arguments will be passed on redering:

{link}
Wiki link to the taxon item
{vernacular}
The "common name" (the value of 1843 or item label) of taxon item in current language
{scientific}
Full scientific name
{scientificshort}
Short scientific name, for example "P. leo" of
  •  

140


Note: Don't use italic style here on scientific names. This style can be set by scientific-name-pattern, scientific-name-repl and other related messages.

  • "<b>{scientificshort}</b>": only display the short scientific name in bold weight
  • "<b>{vernacular} {scientificshort}</b>": display both vernacular and short scientific name in bold weight
  • "[[{link}|{vernacular}]]": display a hyperlink to target taxon with its vernacular name as label

item-format-current-with-vernacular-name Format of instances of

  •  

16521

or 
  •  

310890

. without-vernacular-name means either both 1843 and label (in specified language) are empty, or the vernacular name is the same as 225.

4 named arguments will be passed on rendering, and they are same to item-format-current-with-vernacular-name.

  • "[[{link}|{scientificshort}]]": display a hyperlink to target taxon with its short scientific name as label
  • "[[{link}|{vernacular}]] ({scientficshort})": display both vernacular and short scientific name, also link to target taxon on from vernacular name

scientific-name-pattern, scientific-name-repl Pattern replacement to generate full scientific name. Can be override per rank by scientific-name-pattern-<latinrank> and scientific-name-repl-<latinrank>.

Not the format of scientific-name-pattern and other *pattern* messages are Lua's patterns, which are similar to

  •  

125267

but not identical. Read the manual to know how to write ones.
  • (pattern) "^.+$": match all non-empty strings
    • (repl) "%0": do nothing for replacement, or
    • (repl) "<i>%0</i>": put the scientific name in <i> tag so it can be rendered as italic

short-scientific-name-pattern, short-scientific-name-repl Pattern replacement to generate short scientific name. Can be override per rank by short-scientific-name-pattern-<latinrank> and short-scientific-name-repl-<latinrank>. scientific-name-pattern-<latinrank>, scientific-name-repl-<latinrank> Pattern replcacement to generate full scientific name per rank. The "<latinrank>" is a latin name, can be a instance of

  •  

427626

, or

  •  

713623

. For example "scientific-name-pattern-species" for

  •  

7432

.

  • (scientific-name-pattern-genus) nil: fallback to scientific-name-pattern's "^.+$"
    • (scientific-name-repl-genus) "<i>%0</i>": italicize full scientific name if its rank is
  •  

34740

short-scientific-name-pattern-<latinrank>, short-scientific-name-repl-<latinrank> Pattern replcacement to generate short scientific name per rank. The "<latinrank>" is a latin name, can be a instance of

  •  

427626

, or

  •  

713623

. For example "short-scientific-name-pattern-species" for

  •  

7432

.

  • (short-scientific-name-pattern-species) "^(%w)%w+ (%w+)$": pattern to fetch the first letter of genus name (as %1) and the whole epithet (as %2) from the binomial of a species.
    • (short-scientific-name-repl-species) "<i>%1. %2</i>": for example, the result for
  •  

140

is "P. leo"

scientific-name-replaces or short-scientific-name-replaces Pattern replacements to apply for all full (or short) scientific names, after the name has been processed by pattern-repl pair described above.

The value for each of two messages is not a string but a table. The table contains multiple pattern-repl pairs which will be applied to scientific names.

Note: Lua's table object doesn't sort, so the replacement sequence CAN NOT be guaranteed. DON'T DEPEND ON THE SEQUENCE YOU SAW!

Input Parameters

The "<latinrank>" below is a latin name, can be an instance of

  •  

427626

, or

  •  

713623

. For example "display[cladus]".

Config Options

  • config[lang]: content language (default: en).
  • config[count]: maximum count of taxon to be recursively iterated (default: 10).
  • config[references]: a space-separated list of item ids. The references to favor in case of alternative claims. Optional.
  • config[usetaxa]: a space-separated list of item ids. The taxa to favor in case of alternative claims. Optional.
  • config[link]: if the value is "sitelink" it will use local wiki site links instead of wikidata item links.
  • config[dryun]: used for callback method. Displaying a <pre> block contains wikitext instead of expanding and rendering the template. Dryrun can be used to find parameters to be overrided.
Examples

Lua-ს შეცდომა in package.lua at line 80: module 'Module:Cite' not found.

{{#invoke: taxobox
| taxobox
| qid = Q140
| config[usetaxa] = Q27379
|config[count] = 7
}}

Display Options

display[<latinrank>]: if the value is "n", "no", "false" or "hide", the specified rank (in latin name or QID) will be hide. Otherwise the rank will display.

For example, to hide all clades: Lua-ს შეცდომა in package.lua at line 80: module 'Module:Cite' not found.

{{#invoke:taxobox
|taxobox
|qid=Q140
|display[cladus]=hide
}}


Classic Parameters

  • <latinrank>: The classic taxon parameters used by most
  •  

52496

. All of them can be overrided manually.

  • <latinrank>_authority: The classic taxon authority parameters used by most
  •  

52496

. All of them can be overrided manually.

  • unranked_<latinrank>: The classic unranked parameters used by most
  •  

52496

. All of them can be overrided manually.

If there are more than one clades between two taxon ranks, you can override them by appending [<number>] index to the unranked_<latinrank> parameter.

For example, there are 3 clades between rank genus and rank species. You can override them like this:

{{#invoke:taxobox
|taxobox
|...
|unranked_species[3] = Cladus closest to genus rank
|unranked_species[2] = The middle clade
|unranked_species[1] = Cladus closest to species rank
|...
}}

Output Parameters

The best way to see all output parameters is to use the config[dryrun] parameter:

{{#invoke:taxobox
|callback
|qid=Q140
|config[dryrun]=yes
}}

The result:

Lua-ს შეცდომა in package.lua at line 80: module 'Module:Cite' not found.

All output parameters can be overrided by specifying same name input parameters. For example this will replace

  •  

34740

to "Foo" and 
  •  

2455704

"Bar":

Lua-ს შეცდომა in package.lua at line 80: module 'Module:Cite' not found.


{{#invoke:taxobox
|taxobox
|qid=Q140
|subfamilia=<strong style="color: green">Bar</strong>
|rank[9][taxon]=<strong style="color: red">Foo</strong>
}}

Supported properties

The taxobox currently supports:

  • 18 for taxon images and red list status
  • 31: for
  •  

310890

and 
  •  

14594740

  • 105
  • 141 also mark the taxon extinct if the value is
  •  

237350

  • 171
  • 181
  • 225
  • 248 for references
  • 405
  • 428

  • 566
  • 574
  • 582 mark the taxon extinct if present
  • 697
  • 428 if ICNafp applies, otherwise:
  • 835, otherwise the last name of English language (en) is shown.
  • 944 for authority string format and color.
  • 1843, common name of a language to override the item label of the language

Wikipedia use

This module is designed to be a replacement for Wikipedia taxoboxes. However, it is still unstable and need plenty extra template works to allow a classic

  •
