    dct:description "A three-value ordinal scale — Red, Amber, Green — used as a traffic-light signal for condition, tolerance, or risk level. The colours are intrinsic to the concept identifiers: red means stop/intervene, amber means caution/monitor, green means proceed/within tolerance.\n\nValues are floating-point numbers. The integer part identifies the concept via range lookup. The fractional part expresses relative position within that concept — proximity to a boundary may be used to signal threshold drift, but the interpretation of position is intentionally left to the consuming application.\n\nThis is an abstract base vocabulary. Domain-specific schemes (e.g. cgi:Outlook) use skos:exactMatch to map their concepts onto these three values.";
