TASK DESCRIPTION
I’ve only looked at this sporadically so far, but the category graph in the
Wikidata Query Service seems to be missing a lot of categories. For example:
SELECT * WHERE {
SERVICE <https://query.wikidata.org/bigdata/namespace/categories/sparql> {
BIND(<https://commons.wikimedia.org/wiki/Category:Wikimedia_Foundation_projects>
AS ?category)
?category mediawiki:subcategories ?subcategories.
?subcategory mediawiki:isInCategory ?category.
}
}
| category |
subcategories | subcategory

That’s only six subcateries, rather than the 25 indicated by the
`mediawiki:subcategories` triple (which matches the number on the category page
<https://commons.wikimedia.org/wiki/Category:Wikimedia_Foundation_projects>).
