A substantial part of items at Wikidata merely link disambiguation pages at various Wikimedia sites.
Their features are:
- label: identical or similar in most languages
- description: "Wikimedia disambiguation page" on every item
- sitelinks: links to disambiguation pages on Wikimedia sites
Within Wikidata, these items don't have any function beyond providing interwiki links. Despite that, they seem to create a lot of overhead.
At https://www.wikidata.org/wiki/Wikidata:Bot_requests#Take_care_of_disambiguation_items a few steps have been identified. Eventually these should become sub-tasks of this tracking task.
