Task: Class Definition Understanding (ontology: Earth_Environment/OBOE)

Which of the following definitions best describes 'Characteristic Qualifier'?

A. A the concept is a derived property of an entity that must be combined with concrete characteristics to be used in a measurement. A qualifier is either a base (atomic) or composite qualifier. As an example, the base qualifier minimum can be combined with a characteristic length to create a minimum length qualified characteristic. A composite qualifer is used to combine multiple qualifiers.
B. A base qualifier denotes a simple, atomic qualifier such as average, minimum, and maximum.
C. A the concept describes the type of a Measurement in which the Measurement would follow the associated Protocol to record the value of the associated Characteristic of the associated Entity using the associated Standard. Any of these associated properties may be omitted, in which case the the concept is only constrained by the provided associations. A the concept is a hypothetical construct, in that it is not associated with a particular instance of a Measurement.
D. A composite qualifier combines multiple qualifiers. Each composite qualifier has a base qualifier and a reference to another qualifier. Composite qualifiers are ordered (through hasNextQualifier) to distinguish between the scope of qualifiers, e.g., AverageMinimum versus MinimumAverage.

Answer: A the concept is a derived property of an entity that must be combined with concrete characteristics to be used in a measurement. A qualifier is either a base (atomic) or composite qualifier. As an example, the base qualifier minimum can be combined with a characteristic length to create a minimum length qualified characteristic. A composite qualifer is used to combine multiple qualifiers.
