This file provides a standardized way of associating alternative
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | Identifiers |
|---|
|
from various schemes with
| Gloss |
|---|
| PreSpace | false |
|---|
| t | SNOMED CT components |
|---|
|
.
At any point in time , an alternative
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | Identifier |
|---|
|
within a particular scheme will be associated with one and only one
| Gloss |
|---|
| PreSpace | false |
|---|
| t | SNOMED CT component |
|---|
|
. A
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | SNOMED CT component |
|---|
|
may be associated with zero or more alternative
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | Identifiers |
|---|
|
within a single scheme.
It is important to note that the
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | SNOMED CT component |
|---|
|
and it's alternative
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | Identifiers |
|---|
|
all identify precisely the same real-world object.
Note: The Identifier file is not currently used in the
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | SNOMED CT International Release |
|---|
|
as use of the more flexible
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | Simple map type references set |
|---|
|
structure is preferred for links to alternative codes. The only known current use of this file is for internal identification of components during the content development process.

Only one record with the same
| Specref |
|---|
| RefType | (field) |
|---|
| t | identifierSchemeId |
|---|
|
and
| Specref |
|---|
| RefType | (field) |
|---|
| t | alternateIdentifier |
|---|
|
fields will be current at any point in time. The current record will be the one with the most recent effectiveTime before or equal to the point in time under consideration.
If the
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | active |
|---|
|
field of this record is false ('0'), then the association is
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | inactive |
|---|
|
at that point in time. If the
| Gloss |
|---|
| SpacePreSpace | truefalse |
|---|
| t | active |
|---|
|
field is true ('1'), then there is an identity at that point in time between the
| Specref |
|---|
| RefType | (field) |
|---|
| t | referencedComponentId |
|---|
|
(a
| Gloss |
|---|
| PreSpace | false |
|---|
| t | SNOMED CT component |
|---|
|
) and the alternateIdentifier in the scheme identified by
| Specref |
|---|
| RefType | (field) |
|---|
| t | identifierSchemeId |
|---|
|
.
