Field

Data type

Purpose

id (field)

UUID (data type)

A 128 bit unsigned Integer (data type), uniquely identifying this.

Different versions of a reference set member share the same id (field) but have different effectiveTime (field). This allows a reference set member to be modified or made active (field) (i.e. removed from the active set) at a specified time.

effectiveTime (field)

Time (data type)

The inclusive date or time at which this version of the identified became identifiedbecame the current version.

The current version of this at thisat time T is the version with the most recent effectiveTime (field) prior to or equal to time T .

active (field)

Boolean (data type)

The state of the identified as identifiedas at the specified effectiveTime (field) .

If active (field) = 1 (true) the is theis part of the current version of the set, if active (field) = 0 (false) the is theis not part of the current version of the set.

moduleId (field)

SCTID (data type)

Identifies the that thethat contains this as thisas at the specified effectiveTime (field) .

The value must be a of aof

within the metadata.

refsetId (field)

SCTID (data type)

Identifies the to theto which this belongsthisbelongs.

In this case, set to a of aof

. This indicates the nature of the association between the source and target.

referencedComponentId (field)

SCTID (data type)

The identifier of the source of sourceof the association.

targetComponentId (field)

SCTID (data type)

The identifier of the target of targetof the association.

  • From each to eachto one or more that morethat replace it.

The identified Theidentified by the targetComponentId (field) must be an instance of the same class of as the identified ofas theidentified by the referencedComponentIdfor all |Historical association|apart from the |REFERS TO association TOassociation|.

Within the |REFERS TO association TOassociation|, the referenced ComponentId field must be a and aand the targetComponentIdmust be a.

The targetComponentId (field) is used differently in the |MOVED TO association|. In this case, the targetComponentId (field) does not refer directly to a replacement, but rather to the namespace to which the was thewas moved to. The targetComponentId (field) actually refers to the that thethat represents the namespace. This approach is used since the organization sourcing the may themay not always be able to determine the precise reference that is applicable in the receiving organization (namespace). Thus the responsibility for these references lies with the new responsible (receiving) organization.
