| Field | Data type | Purpose | Mutable | Part of Primary Key |
|---|---|---|---|---|
| id | UUID | A 128 bit unsigned Integer, uniquely identifying this reference set member.Different versions of a reference set member share the same id but have different effectiveTime. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time. | NO | YES (Full /Snapshot) |
| effectiveTime | Time | The inclusive date or time at which this version of the identified reference set member became the current version.Note : In distribution files the effectiveTime should follow the short ISO date format (YYYYMM DD) and should not include the hours, minutes, seconds or timezone indicator.The current version of this reference set member at time T is the version with the most recent effectiveTime prior to or equal to time T . | YES | YES (Full)Optional (Snapshot) |
| active | Boolean | The state of the identified reference set member as at the specified effectiveTime .If active = 1 (true) the reference set member is part of the current version of the set, if active = 0 (false) the reference set member is not part of the current version of the set. | YES | NO |
| moduleId | SCTID | Identifies the SNOMED CT module that contains this reference set member as at the specified effectiveTime .The value must be a subtype of 900000000000443000 |Module (core metadata concept)| within the metadta hierarchy. | YES | NO |
| refsetId | SCTID | Identifies the reference set to which this reference set member belongs. In this case, a subtype descendant of 762676003 |OWL expression type reference set (foundation metadata concept)| | NO | NO |
| referencedComponentId | SCTID | A reference to the SNOMED CT component to be included in the reference set. The concept to which the OWL expression applies. In the case of the 733073007 |OWL axiom reference set (foundation metadata concept)| , the axiom contributes to the definitions to the defintion of the identified concept. | NO | NO |
| owlExpression | String | The text of OWL expression to attach to the component identified by referencedComponentId. | YES | NO |
| moduleId | refsetId | referencedComponentId | owlExpression | Explanatory Notes |
