Example:
The temperature of a fluid stream, the tensile strength of a bolt, the length of a pipeline, the colour of a surface coating, the familiarity of a specialist with a modification procedure, the quality of a window of being open or closed.
Iof usage note:
Qualities are in general subject to change over the lifetime of the bearer. The main IDO device for representing quality changes is through 'datum' individuals: see lis:qualityQuantifiedAs.
Qualities should only be used for root properties such as voltage, pressure, etc. Where there are variants such as nominal, rated, actual voltage, modellers should use lis:Quality for voltage and use a subclass of lis:QualityDatum for the moderator ("nominal", etc.)
