TASK DESCRIPTION

The WDQS is returning results that differ from what is in Wikidata. See https://phabricator.wikimedia.org/T112397 for previous discussions.
Example:
Run the following SPARQL query:

select * where {
  wd:Q21990261 p:P361 ?s .
  ?s ps:P361 wd:Q24772701 .
  ?s prov:wasDerivedFrom ?ref .
  ?ref ?b ?c .
}


I get one row as a result:





srefbc


wds:Q21990261-99529C15-67CB-4166-860D-C4F68336183Ewdref:d472129d472e46ce41323852d3594fefc26467fapr:P854http://www.ebi.ac.uk/interpro/protein/A1Y9I9







If you look on Wikidata: https://www.wikidata.org/wiki/Q21990261#P361, this is missing the stated in on the reference.



If you run the same query with replacing the wd:Q21990261 with wd:Q21135100, you'll see the query works just fine.
