Template:Taxonbar/doc

- - -

There is a documentation subpage housing the metadata about parent template: Taxonbar.

This template is used on approximately 439,000 pages, or roughly 2166% of all pages.
To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

Module:Taxonbar

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:

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.
Click "Show preview" to check placement, and to see which taxon identifiers are automatically pulled from Wikidata.
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

Scarlet macaw (Ara macao)

{{Taxonbar | from=Q243761}} when placed in the Scarlet macaw article: Lua error in Module:Taxonbar at line 160: attempt to index field 'wikibase' (a nil value).

Basic use samples

Taxon identifiers

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

Lua error: callParserFunction: function "#statements" was not found.

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:

Lua error in Module:Taxonbar at line 160: attempt to index field 'wikibase' (a nil value).

Excluded databases

These databases are available at Wikidata, but are excluded by default here (en.wiki) for being non-English.

Additional parameters

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

Example:

{{Taxonbar | emonocot = 280381 }}

On Lilium, the result is:

Lua error in Module:Taxonbar at line 160: attempt to index field 'wikibase' (a nil value).

where the taxon identifier in the eMonocot has been added to those picked up from Wikidata.

Multiple Wikidata entries

Some taxa will exist under multiple names (synonyms) on Wikidata. To add these synonyms, use the |from2=, |from3=, etc., parameters to specify their Wikidata IDs. The parameter |from= / |from1= will be implicitly determined by the Wikidata item linked to the article. While not required, it is preferable to explicitly store the linked Wikidata item in the |from= / |from1= parameter, for maintenance purposes. Parameters |from2=, |from3=, etc., can also be added, for example, if the linked Wikidata item differs from the taxon name of the en:Wikipedia article.

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. You can add taxon identifiers not present in Wikidata by appending the appropriate number to the end of the parameter name — for example, to add emonocot to the second row, use |emonocot2=.

For example, {{Taxonbar|from=Q26972265|from2=Q20717272}}, when placed on the page Dog produces: Lua error in Module:Taxonbar at line 160: attempt to index field 'wikibase' (a nil value).

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: Lua error in Module:Taxonbar at line 160: attempt to index field 'wikibase' (a nil value).

Basionyms

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

For example, both

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

would produce identical taxonbars for Ponerorchis cucullata: Lua error in Module:Taxonbar at line 160: attempt to index field 'wikibase' (a nil value).

or {{Taxonbar|from1=Q43372357|from2=Q21977691|from3=Q164254}} for a customized location: Lua error in Module:Taxonbar at line 160: attempt to index field 'wikibase' (a nil value).
