Overview

IsA: A isA B - For terms A and B, A isA B indicates that A is a subset of B. All terms in BEL represent classes, but given that classes implicitly have instances, one can also interpret A isA B to mean that any instance of A must also be an instance of B. This relationship can be used to represent GO and MeSH hierarchies: pathology(MESH:Psoriasis) isA pathology(MESH:“Skin Diseases”)
