Specref
treferencedComponentId

Specref
RefTypedata type

A reference to a SNOMED CT metadata concept referring to the code system containing the

Gloss
tother-codes
t:other-codes
. This is a subtype of
Concept

Specref
tmapTarget

Specref
RefTypedata type
tString

The

Gloss
tother-code
t:other-codes
associated with the SNOMED CT expression.

Specref
texpression

Specref
RefTypedata type
tString

A 

Gloss
tSNOMED CT expression
 that represents the SNOMED CT definition of the 
Gloss
tother-code
t:other-codes
. This expression may be a 
Gloss
tstated
GlosTermstated view
 or 
Gloss
tinferred view
 of the definition provided that documentation of each identified reference set specifies the view provided.

The expression must conform to the syntax defined in the SNOMED CT Compositional Grammar - Specification and Guide (http://snomed.org/scg).

Specref
tdefinitionStatusId

Specref
RefTypedata type
tSCTID

Indicates whether or not the expression contains a sufficient definition of the

t:other-codes
.

Specref
tcontentOriginId

Specref
RefTypedata type
tSCTID

Indication of whether concept was initially in one of the terminologies (SNOMED CT or

Gloss
tother-codes
t:other-codes
) and added to the other as part of mapping or was in both terminologies at the outset. Values are subtype children of
