Mapping behaviour using item validity

Overview

Fusion Registry's Structure Mapping function allows datasets to be transformed from one structure and classification scheme to another. Mapping of classifications is performed using Codelist Maps which define how Codes in one Codelist map to those in another.

When defining Codelist Maps, a Validity Period on a Code by Code basis which describes the period in time when the mapping will be applied. When executing a transformation using the Codelist Map, Fusion Registry will apply the mapping if the series' observations fall within the specified period.
