vocabularies

The intended-use role names of refuse bins that share one slot-profile (a lidded refuse container keyed by capacity, lid mechanism, wheels and colour) and differ only by usage context: dustbin (a general refuse bin), kitchen bin, office bin, sanitary bin and outdoor bin. A growing vocabulary (L13). These are usage-context names orthogonal to size/lid/wheels — 'wheelie bin' (a wheel count) and 'swing bin' (a lid mechanism) are deliberately NOT values here.

Answers the question: waste bin type.
