Each

Gloss
Spacetrue
tconcept
is defined by a set of
Gloss
Spacetrue
trelationships
to other
Gloss
Spacetrue
tconcepts.
The resulting definition may be sufficient to distinguish the
Gloss
Spacetrue
tconcept
from its parents and siblings in the
Gloss
Spacetrue
tsubtype hierarchy
in which case the
Gloss
Spacetrue
tconcept
is considered to be
Gloss
Spacetrue
tsufficiently defined.
GlosTermsufficiently defined concept
If the definition is not sufficient to distinguish the
Gloss
Spacetrue
tconcept
from its parents and siblings, the
Gloss
Spacetrue
tconcept
is said to be
Gloss
Spacetrue
tprimitive.
The
Gloss
Spacetrue
tconcept
contains a field that is set to indicate whether its definition status is
Gloss
Spacetrue
tprimitive
or
Gloss
Spacetrue
tsufficiently defined.

Stated definition view

A stated

Gloss
Spacetrue
tconcept
 definition is the set of
Gloss
trelationships
 (and groups of
Gloss
Spacetrue
trelationships)
that an author
Gloss
Spacetrue
t(modeler)
has stated to be
Gloss
Spacetrue
tdefining characteristics
of a
Gloss
Spacetrue
tconcept.
The
Gloss
Spacetrue
tstated view
is maintained in the
Gloss
Spacetrue
tSNOMED CT
editing  editing environment and is reviewed and modified during the process of editing a revised edition of
Gloss
Spacetrue
tSNOMED CT.
The
Gloss
Spacetrue
tstated view
is distributed in a format similar to the relationship file.

An inferred

Gloss
Spacetrue
tconcept
definition may include the set of non-redundant defining
Gloss
trelationships
 (and
Gloss
Spacetrue
trelationship groups
groups) that are known to be true. This includes those stated and others inferred by inheritance from stated
Gloss
Spacetrue
tsupertype ancestors.
However, any
Gloss
trelationships
 (or
Gloss
Spacetrue
trelationship groups)
that are supertypes of other
Gloss
trelationships
 (or
Gloss
Spacetrue
trelationship groups)
are redundant and are not included in this view.
