Overview of current conservation and restoration models

This report is a review of published work describing models for conservation data based on the CIDOC-CRM and its extensions. The report is an analysis of the new classes and properties recommended, as well as the mapping decisions adopted for the published models. The report identifies common practices and recommends ways of harmonising the different models. It proposes areas where further modelling work is needed and attempts to organise this work in conceptually coherent groups from a conservation perspective.
