Upper and mid-level hierarchical structure of the ONS showing how relevant nutritional concepts have been related to each other. Considering the large number of concepts and relations defined in the ONS, further detailed relations are not shown here. The terms in green boxes are ONS-specific terms, while terms in other color boxes are imported from existing ontologies (i.e., BFO, OBI, IAO, CHEBI, SIO, FOODON). Dotted arrows represent “is_a” semantic relations, while solid arrows represent other types of semantic relations
