Property:Has type
From Placeography
has type is a special property in Semantic MediaWik] with a built-in meaning: it assigns a type to a property. Special:Types lists the types available in the wiki.
For example, the page for Property:Population would specify [[has type::Number]]. "Has type" assumes its value is in the Type namespace, so you can omit Type:.
This property is a special property in this wiki.
