Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Reference_Set_Member_Id | A field, uniquely identifying this reference set member. Different versions of a reference set member share the same ID but have different Effective_Date. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time. | integer | level : Ratiorequired : 1 |
Effective_Date | The inclusive date at which this version of the identified reference set member became the current version. | date | required : 1 |
Is_Active | The state of the identified reference set member as at the specified Effective_Date. If active= true, the reference set member is part of the current version of the set, if active=false, the reference set member is not part of the current version of the set. | boolean | required : 1 |
Module_Id | Identifies the SNOMED CT module that contains this reference set member as at the specified Effective_Date. | integer | level : Ratiorequired : 1 |
Definition_Status_Id | Specifies if the concept version is primitive or fully defined. | integer | level : Ratiorequired : 1 |
