About

[uredi kodo]

This template is designed to be called from {{Taxobox/core}} or a related template, and tracks pages which may be candidates for a {{Taxonbar}}.

If no {{Taxonbar}} exists on the transcluded page, the page's Wikidata item is checked against this whitelist of acceptable primerek od (P31)s/podpomenka od (P279)s, and this blacklist of unacceptable properties.

If an acceptable instance/subclass is found, then the page is categorized as:

If no acceptables nor unacceptables are found, then it is categorized as:

If no acceptables & at least 1 unacceptable is found, then no categorization is performed.
