Ah. Thanks. I was going to ask why this ranking thing wasn't exposed in the interface, but now I see those little arrows over on the far left.

Hi Eric,

this is because the values that are not present are not the "best statements". That means that there are statements of a higher rank (https://www.wikidata.org/wiki/Wikidata:Glossary#Rank).

It's still possible to access these values, please have a look at https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#Truthy_stat....

Cheers, Marius

I know of two cases where there are statements in the wikibase which have not been translated to wdt's.

One is for spouses of Bradd Pitt, which retrieves wdt for Angelina Jolie, but poor Jennifer Anniston is left out in the cold:

Select * Where { wd:Q35332 ?p ?o. Filter Regex(Str(?p), "P26$")

} ==> p o http://www.wikidata.org/prop/direct/P26 http://www.wikidata.org/entity/Q13909 http://www.wikidata.org/prop/P26 http://www.wikidata.org/entity/statement/Q35332-9167b7b7-422a-6027-0449-e7d2096900e5 http://www.wikidata.org/prop/P26 http://www.wikidata.org/entity/statement/q35332-E60D2807-57AF-40D3-90D8-BC89F5AC3140

This second wdt is also absent from the ttl cache: https://www.wikidata.org/wiki/Special:EntityData/Q35332.ttl

The analogous query for Humphrey Bogart retrieves all four of his marriages, each of which has beginning and end dates, just as Brad's marriages do.

Another example is Barack Obama's birthplace : http://tinyurl.com/ya7f948a (returns only the hospital he was born at, and ignores Honolulu)

Contrast this with more complete coverage of Putin's birthplace: http://tinyurl.com/ya7f948a

Is this evidence of a bug?

Thanks,
