Purpose
A
| Concept |
|---|
| t | 900000000000512005|Query specification type reference set| |
|---|
|
allows a serialised query to represent the membership of a subset of
| Gloss |
|---|
| PreSpace | false |
|---|
| t | SNOMED CT components |
|---|
|
. A
query contained in the
| Gloss |
|---|
| PreSpace | false |
|---|
| t | reference set |
|---|
|
is run against the content of
to produce a subset of
,

| PreSpace | false |
|---|
| t | descriptions |
|---|
|
or
| Gloss |
|---|
| PreSpace | false |
|---|
| t | relationships |
|---|
|
. The query is referred to an intensional definition of the subset. It can be run against future releases of
to generate an updated set of subset members.
The members of the resulting subset may also be represented in an enumerated form as a
| Gloss |
|---|
| PreSpace | false |
|---|
| t | Simple reference set |
|---|
|
. An enumerated representation of a subset is referred to as an extensional definition.

query is an extensional representation of the subset of
which can be represented as a
