Concept help - Property
A property is a characteristic of an object class of interest. For example, the object class Person can have characteristics such as sex and date of birth. These characteristics are referred to as properties.
The union of a specific property with a specific Object Class creates a Data Element Concept. The above mentioned examples create the data element concepts Person—sex and Person—date of birth.
ISO/IEC 11179-3 Section 11.2.2.2Property is a class each instance of which models a property (3.2.100), a quality common to all members of an object class (3.2.88). A property may be any feature that humans naturally use to distinguish one individual object from another. It is the human perception of a single quality of an object class in the real world. It is conceptual and thus has no particular associated means of representation by which the property can be communicated.
A Property may have a data_element_concept_property association (11.2.3.1) with zero or more Data_Element_Concepts (11.2.2.3).
Tips for creating Properties
- Be generic: A property should apply to all members of an Object Class
- Properties are unitless: They should be describe some aspect of a thing, without prescribing how that aspect is measured. For example, height is an attribute of all people regardless of how it is measured.
