Policy and Guidelines for Incrimental Update

Incremental update is a component of the ICSM Harmonised Data Model.  For this purposes incremental update is defined as:

a data transfer system that enables suppliers to supply only information that has been affected by change between two versions of a dataset and for users to be able to incorporate those changes into their data .

This document includes the policy for incremental update to be adopted for ICSM-sponsored datasets, and guidelines as to how the policy might be applied.  The approach that has been adopted is one of setting minimal standards because there are several different approaches to incremental update already implemented by different jurisdictions and because data users as well as suppliers also participate in the incremental update process.  The users may need to modify their approach to suit their individual circumstances.
