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$")
This second wdt is also absent from the ttl cache:
The analogous query for Humphrey Bogart retrieves all four of his
marriages, each of which has beginning and end dates, just as Brad's
Another example is Barack Obama's birthplace :
(returns only the hospital he was born at,
and ignores Honolulu)
Contrast this with more complete coverage of Putin's birthplace:
Is this evidence of a bug?
