Incorrect collection (P195) statements

I noticed someone introduced collection of the National Gallery Prague (Q101034183) and Collection of old art (National Gallery Prague) (Q108806424). These items shouldn't be used in collection (P195). This property is used to record who the collection holder is, not to record some meta item or what subcollection it's in. If you want to record this, please propose a new property. I corrected the constraints to reflect this. Multichill (talk) 16:29, 21 August 2022 (UTC)
