UFO meta-categories
UFO categories
The 8 UFO foundational meta-categories borne by the 37 OPDA classes — from the inert
opda:ufoCategory facet (an annotation-graph-only documentary annotation;
UFO-informed, not UFO-grounded). The classification doctrine
keeps kinds as facets, not subclass trees (ODR-0027).
