Discussion

Make sense

Why don't we have simply a have a class "people born in whatever" which would have a definition like "people with a <born in: Whatever> statement and a "people born in whatever" <category : Category:People born in whatever> ? I think these kind of properties are useless. author  TomT0m / talk page 14:23, 28 September 2015 (UTC)

What's different from last time you asked the question? --- Jura 14:28, 28 September 2015 (UTC)

Strange bug in Constraint

Hi,

There is a {{Constraint:Type|classes=Q7703766, Q7275|relation=instance}} but apparently something is wrong (though this syntax is give as an example on Template:Constraint:Type) as a lot of territory (Q7703766) are listed as violation on Wikidata:Database reports/Constraint violations/P1464. Right now, there is 16254 violations on 16762 uses, near 97%...

Could someone see what is wrong and why ? Poke Ivan A. Krestinin
