Property:Subproperty of
From D&D Wiki
"Subproperty of" is a declarative predefined property to define that a property is a subproperty of another and is provided by Semantic MediaWiki. This property is pre-deployed (also known as special property) and comes with additional administrative privileges but can be used just like any other user-defined property.
subproperty of is a special property in Semantic MediaWiki with a built-in meaning: it lets you indicate that one property is a subproperty of another.
