Further information: Help:Taxon identifiers

Description

This metadata template links Wikipedia articles to various biological and taxonomic databases. Taxonbar displays these links as short strings, indicating the unique identifier each database has assigned the taxon for catalogue purposes.

Taxonomic identifiers of each taxon are stored and retrieved from each taxon's corresponding Wikidata entry, but can be overridden in individual articles with locally entered data. Adding the data to Wikidata is preferable.

This project is based on the work of {{Authority Control}} and Wikidata:WikiProject Taxonomy. If you are a template editor or Wikipedia administrator, you may contribute at Module:Taxonbar. Please discuss ideas/thoughts for improvement or use on Template:Taxonbar/talk.

Taxonbar is placed below all navigation templates, except Authority control (not shown here).

Position

Please place Taxonbar correctly. As a metadata template, Taxonbar should be placed:

• Below all references, footnotes, and external links.
• Below all navigation templates—except Authority control
• Above the Authority control template.
• Above all [[Category:]] and stub template codes in the editor.

Usage

Add Taxonbar to an article:

1. In Source editing mode, insert {{Taxonbar|from=}} below all other navigation templates except Authority control — it is preferable to add the from = QID parameter even if just a single Wikidata item points to the article.
2. Click "Show preview" to check placement, and to see which taxon identifiers are automatically pulled from Wikidata.
3. If you have more identifiers to add, consider adding them to the article's Wikidata item, so that all versions of Wikipedia automatically benefit. Be careful not to edit the structure or names of Wikidata taxa until you have become familiar with Wikidata:WikiProject Taxonomy and Wikidata:WikiProject Taxonomy/Tutorial.

Basic code:

{{Taxonbar|from=}}

Taxon example

Pileated woodpecker (Dryocopus pileatus), syn. Picus pileatus

{{Taxonbar|from=Q930712}} when placed in the Pileated woodpecker article:

Taxon identifiers

For databases supported by Wikidata:WikiProject Taxonomy, see d:Wikidata:WikiProject Taxonomy#Databases.

The template can automatically get its information from the following properties on Wikidata. This is configured in Module:Taxonbar/conf.

List of taxon identifiers

Manual identifiers

Some taxon identifiers not currently in Wikidata can be added via additional parameters listed above; however, adding the data to Wikidata is preferable, so that all versions of Wikipedia automatically benefit.

Example:

{{ Taxonbar | powo = urn:lsid:ipni.org:names:30009317-2 }}

On Lilium, the result is the following, where the taxon identifier in the Plants of the World Online has been added to those picked up from Wikidata:

If there are multiple Wikidata entries resulting in multiple rows, the row to which an identifier is added can be specified by appending a number matching the relevant |from#= parameter.

A Wikispecies page can be also added manually. However, it is preferable to link it to the Wikidata item; this can be done at the Wikidata page within the "Multilingual sites" section, entering "species" as the "wiki".

Parameter	Database	Property URL/Interwiki link
Wikispecies	Wikispecies	Wikispecies:$1

Hide specific identifier (optional)

Individual identifiers listed in the table above can be removed/hidden from the bar by setting the corresponding parameter to no. This is useful when trying to reduce the number of unhelpful links within Taxonbar. Spaces are optional. There is no sense in removing too many identifiers, for example: removing plant or fungi identifiers from an animal taxon would have no effect, as these parameters will not show up on an animal taxon in the first place. It is best to preview {{Taxonbar}} on the page and decide what entries provide little relevant data. Plant species will have the most entries and are most likely in need of hiding some entries.

Example: To remove FOC, IPNI, and AFPD, the code would look like:

{{ Taxonbar | foc = no | ipni = no | apdb = no }}

On Coffea arabica, the result is:

Displaying excluded databases (optional)

These databases are available at Wikidata but are excluded by default on the English-language Wikipedia as they are not in the English language. They can be included in the {{taxonbar}} by setting the corresponding parameter to yes (e.g. |CoL-Taiwan=yes), which will then retrieve the value from Wikidata, or by setting the value of the parameter manually (e.g. |CoL-Taiwan=395235).

Multiple Wikidata entries

The parameter |from= / |from1= will be implicitly determined by the Wikidata item linked to the article. For maintenance purposes it is preferable to explicitly provide the linked Wikidata item in the |from= / |from1= parameter, although it is not strictly required. If it is not provided the article will be listed at Category:Taxonbars without from parameter.

Parameters |from2=, |from3=, etc., can also be added, for example, if the linked Wikidata item differs from the taxon name of the English-language Wikipedia article. Some taxa exist under multiple names (synonyms) on Wikidata. To add these synonyms, use the |from2=, |from3=, etc., parameters to specify their Wikidata IDs. If there is more than one row, the taxon name from Wikidata will be shown in the leftmost column — to overwrite this, use the |title= / |title1=, |title2=, |title3=, etc. parameters.

For example, {{Taxonbar|from=Q26972265|from2=Q20717272}}, when placed on the page Dog produces:

The same approach can be used when monotypic taxa have a single article, but there are multiple entries in Wikidata. For example, at Haptanthus, which covers the genus and its sole species, {{Taxonbar|from1=Q15715555|from2=Q133951}} produces:

You can manually add taxon identifiers not present in Wikidata to a specific row by appending the appropriate number to the end of the parameter name — for example, to add an inaturalist identifier to the second row, use |inaturalist2=.

Basionyms

Basionyms available on Wikidata (via (P566)) are automatically appended. You may also manually specify the basionym via |from#= to manually specify its position.

For example, both

{{Taxonbar|from1=Q43372357|from2=Q164254}} and

{{Taxonbar|from1=Q43372357|from2=Q164254|from3=Q21977691}}

would produce identical taxonbars for Ponerorchis cucullata:

However, changing the order of the IDs will alter their position in the taxonbar so

{{Taxonbar|from1=Q43372357|from2=Q21977691|from3=Q164254}}

produces a taxonbar with the basionym in a different position:
