spatially disjoint from https://github.com/obophenotype/uberon/wiki/Part-disjointness-Design-Pattern 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 BFO_0000051 exactly 0 (BFO_0000050 some ?Y) A is spatially_disjoint_from B if and only if they have no parts in common 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. mereotopologically related to pending final vetting
