What flows is one GINC research field at the finest level; there are 10,533. Direct fields carry a OpenAlex code themselves. Under fields carry none, but sit beneath a field that does, so OpenAlex has a place for them one level up. Gap is what one side has and the other does not: on the OpenAlex side, GINC fields OpenAlex has no place for at all; on the GINC side, fields that reach no domain. Group bars are scaled to a large group; the gap rows to every field.

GINC's research fields are the union of these classifications. Where two or more name the same field it is one GINC field carrying each of their codes, so Fields is lower than Entries where a classification's entries merged with each other's, and the same where none did. A field takes its name and its place in the hierarchy from the first classification in this list that has it.
