Each

Gloss
Space true t concept

is defined by a set of

Gloss
Space true t relationships

to other

Gloss
Space true t concepts.

The resulting definition may be sufficient to distinguish the

Gloss
Space true t concept

from its parents and siblings in the

Gloss
Space true t subtype hierarchy

in which case the

Gloss
Space true t concept

is considered to be

Gloss
Space true t sufficiently defined. GlosTerm sufficiently defined concept

If the definition is not sufficient to distinguish the

Gloss
Space true t concept

from its parents and siblings, the

Gloss
Space true t concept

is said to be

Gloss
Space true t primitive.

The

Gloss
Space true t concept

contains a field that is set to indicate whether its definition status is

Gloss
Space true t primitive

or

Gloss
Space true t sufficiently defined. GlosTerm sufficiently defined concept

The figure below  illustrates the abstract logical model of a

A

Gloss
Space true t relationship

that is part of a relationshipGroup

Specref
RefType (field) t relationshipGroup

is only regarded as redundant if the relationshipGroup

Specref
RefType (field) t relationshipGroup

as a whole subsumes another relationshipGroup

Specref
RefType (field) t relationshipGroup

. This is the view expressed in the standard

Gloss
Space true t SNOMED CT

distribution and this same view also forms part of the long

Gloss
t normal form.
