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

Which of the following definitions best describes 'Characteristic'?

A. A the concept of an entity is one that is measurable within the physical world. A the concept includes primary and derived physical dimensions (e.g., length, mass, area, density). The measured value assigned to a the concept may be a quantity (a numerical value) or a quality (a category), including both nominal and ordinal categories.
B. A the concept represents a property of an entity that can be measured (e.g., height, length, or color). A the concept of an entity is observed through a measurement, which further asserts a value of the the concept for the entity. A the concept type (e.g., "height") can be associated with many different entities, whereas an individual the concept (a particular occurrence of the "height" the concept) is associated to exactly one entity.
C. An the concept is used to identify or name an entity either globally or within a context, such as a name of a lake or a tag number assigned to a tree. Unlike a MeasuredCharacteristic, an the concept is assigned and not measured.
D. 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.

Answer: A the concept represents a property of an entity that can be measured (e.g., height, length, or color). A the concept of an entity is observed through a measurement, which further asserts a value of the the concept for the entity. A the concept type (e.g., "height") can be associated with many different entities, whereas an individual the concept (a particular occurrence of the "height" the concept) is associated to exactly one entity.
