 | It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the
encyclopedia's categorization scheme
.
More information:
- This category is
hidden
on its
member pages
—unless the corresponding
user preference
(Appearance → Show hidden categories) is set.
- These categories are used to track, build and organize lists of pages needing "attention
en masse
" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
- These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (
discriminated by classifications
).
- Typically, tracking categories are automatically populated by templates invoked in pages or by the MediaWiki software (see
Special:TrackingCategories
for an overview of the latter).

This is an error tracking category for
{{
Taxonbar
}}
templates which do not have a
|from#=
parameter corresponding to the Wikidata item (also referred to as 'entity' or 'QID') which points to the Wikipedia article.
Possible reasons for this include:
- it is most likely that the Wikidata item that once pointed to the categorized page has changed, or
- one or more
|from#=
parameters contain
garbage
(less likely; see
Category:Taxonbars with invalid from parameters
), or
- the page was copied as a template and the creator forgot to update the
|from=
parameter, or
- Wikidata has separate items for a taxon and a topic associated with the taxon (e.g., a disease and its causal agent, or a vegetable and the plant species that produces it), and the Wikipedia article is linked to the associated concept at Wikidata.
Please notify
