title: Condition Assessment
description: 'A qualitative conservation inspection (CRMsci E14 Condition Assessment)
  recording the condition state of a heritage object or place, encoded as a GeoJSON/JSON-FG
  Feature: CIDOC-CRM/CRMsci attributes nest under `properties` (GeoJSON convention),
  and a `choType` property carries the CRMsci class as a second alias to `@type`,
  alongside the fixed `type: "Feature"`. Localisation is optional: `geometry` may
  be `null` (no spatial localisation), an embedded GeoJSON geometry, or given by reference
  via topology (`topology`, see ogc.geo.topo.features.topo-feature) to avoid duplicating
  coordinates already recorded on the affected object.'
