TASK DESCRIPTION

@Daniel_Mietchen submitted this query:

SELECT DISTINCT ?item ?pubyear WHERE {
  ?item wdt:P577 ?pubdate;
        wdt:P31 wd:Q13442814.
  BIND(year(?pubdate) AS ?pubyear).
  MINUS { ?item schema:description ?itemDescription. }
}
LIMIT 10

Currently, it returns these results:





The first two items have been deleted, the rest are redirects. As far as I know, WDQS isn’t supposed to return deleted items at all, and redirects should only appear when explicitly selected with owl:sameAs, so I assume this must be stale data.



This may be a dupe of T136393, and I suppose T153513 would resolve this issue.
