Abstractions by Domain Group

The 8 groups the canonical domains roll up into — a reading aid for the roster, not a second taxonomy. A domain belongs to exactly one group, declared in the roster itself; nothing stores a group on an entity. 1,524 primes and 11,102 domain-specific abstractions are placed below. See also the Shape of the Abstraction Space — these same groups drawn as a measured similarity map.
