Here's a query for showing all of the proeprties that are missing P7087. (Thanks to Tagishsimon for helping create this query!)

SELECT DISTINCT ?item ?itemLabel 
WHERE 
{
  ?item wdt:P31/wdt:P279* wd:Q18616576.
  FILTER NOT EXISTS {?item wdt:P7087 [] .} # Omit properties that have an "inverse label item" statement.
  FILTER NOT EXISTS {?item wdt:P1696 [] .} # Omit properties that have an "inverse property" statement.
  FILTER NOT EXISTS {?item wdt:P31/wdt:P279* wd:Q15720608 .} # Omit quantifiers (comment this line to show.)
  ?item wikibase:propertyType wikibase:WikibaseItem. # Only show properties with "item" datatypes.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". } 
}

What is the difference between property "inverse Property" and "inverse label item"

The property "inverse property" seems to be the same. The only difference i see is that "inverse property" targets another property, while this property targets an inverse property label item.

But i cant see the difference between a property label item and a property.

I cant label both as same as, because that property only targets items and not properties. R Focke (talk) 09:12, 12 April 2023 (UTC)
