An attribute denotes characteristics of an entity. At this stage, "Quality" is the only direct subclass of "Attribute", whose subclasses denote qualitative properties such as sex ("Female", "Male", "Hermaphrodite"), zygosity ("Hemizygous", "Heterozygous", "Homozygous"), etc. The object property "has quality" (or subproperties thereof) should be utilized to express qualities of entities. The "hasAttribute" object property should be used to denote relationships to "Object" or "Process" instances, unless there is a better object property suitable to represent the relationship between entities.
