Table 11: Non-redundant attribute views of sample concepts
See Figure 14
C. | Injury disorder |
| morphology |=| injury |
E. | Bone or arm injury | (primitive)
| morphology |=| injury |
G. | Severe upper limb laceration | (primitive)
| site |=| upper limb structure |
| morphology |=| injury |
| severity |=| severe |
J. | Fracture (disorder) |
| site |=| bone structure |
| morphology |=| fracture |
L. | Severe laceration of hand |
| site |=| hand structure |
| morphology |=| injury |
| severity |=| severe |
Note
Although the morphology | laceration | is not specified
in the example | severe upper limb laceration | refined
to the site hand fully defines this concept.
In a complete view (including supertypes and
attributes) this difference is clear.
D. | Injury of upper limb |
| site |=| upper limb structure |
| morphology |=| injury |
F. | Bone or joint injury | (primitive)
| morphology |=| injury |
H. | Hand injury |
| site |=| hand structure |
| morphology |=| injury |
K. | Joint injury |
| site |=| joint structure |
| morphology |=| injury |
M. | Scaphoid fracture |
| site |=| scaphoid bone structure |
| morphology |=| fracture |
2.2.1.3.2.3.2.3. Primitive differential attribute view of concept definitions
The primitive differential view includes only non-redundant defining relationships (and relationship groups)
that are not present in the sum of the definitions of the set of primitive supertype concepts.This view provides
a minimal attribute view which is semantically complete when combined with one of the primitive supertype
views.
A relationship that is part of a relationship group is only regarded as redundant if the relationship group as a
whole subsumes another relationship group.
