description: 'Holds between C and P if C owl:subClassOf P. Note that in this model,
most classes are metaclasses (see ''owl class''), where these metaclasses may
represent *groupings* or specific countable elements or species. We provide
two different sub-properties of subclass of for two cases: (1) subtype_of, which
connects grouping classes (e.g. alkane is_a hydrocarbon; alpha-amino-acid is_a
amino-acid), (2) classified_by, which connects a specific element to a grouping
class (e.g. methane is_a hydrocarbon; iron is_a metal; serine is_a amino-acid)'
