# Worked example: accessibility as MATCHABLE facets. One open vocabulary of
# gmeow:AccessibilityFacets (wheelchair, step-free, visual, auditory, cognitive …)
# is used across three relations: what a location HAS
# (gmeow:hasAccessibilityFeature), what it lacks as a gmeow:hasBarrier, and what an
# agent NEEDS (gmeow:hasAccessibilityNeed). Because need and feature draw on the
# same vocabulary, "Dana needs wheelchair access" and "the library has wheelchair
# access" MATCH directly. A reified gmeow:AccessibilityAssertion records who
# claims which facet, with a gmeow:assertionPolarity (feature / barrier / limited).
