Wikidata:Types of part-whole relations
This article describes some types of part-whole relationships.
Properties
editThese are some properties that differentiate the types of part-whole relations:
- Configurational: "whether or not the parts bear a particular functional or structural relationship to one another or to the object they constitute"[1]
- Functional: "Parts are/are not in a specific spatial/temporal position with respect to each other which supports their functional role with respect to the whole"[2]
- Homeomerous: Whether the parts are the same type as their whole[2][1]
- Invariance[1]/Seperable[2]: Whether the parts can be separated from the whole without changing the whole

Wikidata properties: has part(s) (P527)/member of (P463)

Properties
editNot part-whole relationships
editThese types of relationships may be confused to be part-whole relationships but they are not.
Example: If something is inside a room, that doesn't mean it's part of it.
Wikidata properties: contains (P4330)/container (P9813), enclosure (P3158)
Example: Just because the Mississippi River connects to the Gulf of Mexico and shares a body of water with it does not mean it is a part of it.
Wikidata properties: connects with (P2789), tributary (P974)
Example: A book is part of the set of all books, but that doesn't mean it is part of a "book". We use instance of (P31) instead.
Wikidata property: subclass of (P279), instance of (P31)
