curator note

Note that it would be possible to use the relation to label the relationship between a near infinite number of structures - between the rings of saturn and my left earlobe. The intent is that this is used for parsiomoniously for disambiguation purposes - for example, between siblings in a jointly exhaustive pairwise disjointness hierarchy


A is spatially_disjoint_from B if and only if they have no parts in common

editor note

There are two ways to encode this as a shortcut relation. The other possibility to use an annotation assertion between two classes, and expand this to a disjointness axiom.

expand expression to

BFO_0000051 exactly 0 (BFO_0000050 some ?Y)
