This document provides guidance on how Generation Victoria (GenV), led by the Murdoch Children's Research Institute (MCRI), can optimally support and ‘future-proof’ the use of data for spatial research with the GenV cohorts of children and parents. The priority is what must be achieved ‘now for now’ (essential to GenV’s immediate functioning) or ‘now for later’ (if not enabled now, would be difficult or impossible to achieve later or would result in substantial missing data). It also notes ‘later for later’ activities that are important but can be deferred until after recruitment without loss of data, utility or value.
