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.

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

Add Taxonbar to an article:

{{Taxonbar|from=}}

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

Examples of articles demonstrating its use include:

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

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".

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:

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).

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 available on Wikidata (via basionym (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:

Arabica coffee, Coffea arabica

Jaguar, Panthera onca

Fly agaric, Amanita muscaria

Lactobacillus acidophilus

Plasmodium falciparum
