A hierarchy in which a set of concept model attributes are linked to a more general attribute.

Notes

• Attribute hierarchies are represented in release files:
  • as subtype relationships in the relationship file.
  • as OWL SubObjectPropertyOf() axioms in the OWL axiom reference set file

Examples

• Attribute Hierarchy for "Proper part of"

  774081006 |Proper part of|
        733931002 |Constitutional part of|  
        733930001 |Regional part of|
        733932009 |Systemic part of|

• Attribute Hierarchy Represented as Three "is a" Relationships

  733931002 |Constitutional part of|   116680003 |is a|   774081006 |Proper part of|
  733930001 |Regional part of|   116680003 |is a|   774081006 |Proper part of|
  733932009 |Systemic part of|   116680003 |is a|   774081006 |Proper part of|

• Attribute hierarchy represented by three OWL expressions

  SubObjectPropertyOf(:733930001 :774081006)
  SubObjectPropertyOf(:733931002 :774081006)
  SubObjectPropertyOf(:733932009 :774081006)
