, uniquely identifying this . Different versions of a reference set member share the same id but have different effectiveTime | Specref |
|---|
| RefType | (field) |
|---|
| t | effectiveTime |
|---|
|
. This allows a reference set member to be modified or made active (i.e. removed from the active set) at a specified time. |
| effectiveTime | Time | The inclusive date or time at which this version of the identified | Gloss |
|---|
| Space | true |
|---|
| t | reference set member |
|---|
|
became the current version. The current version of this | Gloss |
|---|
| Space | true |

| t | reference set member |

|
at time T is the version with the most recent effectiveTime | Specref |
|---|
| RefType | (field) |

| t | effectiveTime |

|
prior to or equal to time T . |
active | Boolean | The state of the identified | Gloss |

| t | reference set member |
|---|
|
as at the specified effectiveTime | Specref |

|
. If active = 1 (true) the | Gloss |
|---|
| Space | true |

| t | reference set member |

|
is part of the current version of the set, if active = 0 (false) the | Gloss |

is not part of the current version of the set. |

within the metadata . |
refsetId | SCTID | Identifies the to which this | Gloss |

|
belongs. In this case, set to a of | Concept |
|---|
| t | 447258008|Ordered type reference set| |

|
|
| referencedComponentId | SCTID | The identifier of a | Gloss |
|---|
| Space | true |
|---|
| t | SNOMED CT component |
|---|
|
that is included in the ordered list of alternative hierarchy. |
| order | Integer | Specifies the sort order of the list. The list is ordered by applying an ascending sort of the order value. The value of order =1 represents the highest priority. A value of '0' is not allowed. Duplicate values are permitted and the sort order between two members with the same order value is not defined. If the linkedToId | Specref |
|---|
| RefType | (field) |
|---|
| t | linkedToId |
|---|
|
value is not 0, sorting occurs within subgroups that share the same linkedToId | Specref |
|---|
| RefType | (field) |
|---|
| t | linkedToId |
|---|
|
. Note: The name "order" is a reserved word in some database environments. Please consider this when using this column. |
linkedToId | RefType | (field) |
|---|
| t | linkedToId |
|---|
|
| SCTID | The identifier of a | Gloss |
|---|
| Space | true |
|---|
| t | SNOMED CT component |
|---|
|
that acts as a grouper or hierarchy node, collecting together a subgroup from within the list. This field either enables | Gloss |

| Space | true |
|---|
| t | reference set member |
|---|
|
linked into a number of subgroups. These subgroups can be nested allowing representation of alternative hierarchies. To link members into a subgroup, all components in the same subgroup should reference the same . This can either be a component that represents the name of that subgroup or the first member of the subgroup. In the latter case, the first row of each subgroup will contain the same identifier in referencedComponentId and linkedToId and | Specref |
|---|
| RefType | (field) |
|---|
| t | linkedToId |
|---|
|
and with order =1. To link a number of to a single parent , one member record should exist per , with the referencedComponentId | Specref |
|---|
| RefType | (field) |
|---|
| t | referencedComponentId |
|---|
|
field referencing the parent and this field referencing the . The order field is then used to order the under the parent . For ordered lists that do not require grouping or hierarchical arrangement the value of linkedToId | Specref |
|---|
| RefType | (field) |
|---|
| t | linkedToId |
|---|
|
should be the digit zero (0). |
