A Qualitative Value is an entity that represents the state of a certain qualitative Product or Service Property. Qualitative Values are either Literal Values or Enumerative Values. Literal values are represented just as literals with respective datatype properties. For all other enumerative values, instances of this class are being created. An instance of this class represents a qualitative value for an object property. Examples: the color "green", the power cord plug type "US". Note: Currently, neither value sets nor ordinal relations between values are supported. This can be implemented when needed by importing and refining GoodRelations.
