Only one record with the same

Specref
RefType(field)
tidentifierSchemeId
and
Specref
RefType(field)
talternateIdentifier
fields will be current at any point in time. The current record will be the one with the most recent effectiveTime before or equal to the point in time under consideration.

If the

Gloss
Spacetrue
tactive
field of this record is false ('0'), then the association is
Gloss
Spacetrue
tinactive
at that point in time. If the
Gloss
Spacetrue
tactive
field is true ('1'), then there is an identity at that point in time between the
Specref
RefType(field)
treferencedComponentId
 (a
Gloss
tSNOMED CT component
) and the alternateIdentifier in the scheme identified by
Specref
RefType(field)
tidentifierSchemeId
.
