title: Heritage Object Feature
description: "Feature-envelope wrapper for ogc.heritage.heritage-object: a spatially
  located heritage object encoded as a GeoJSON/JSON-FG Feature, or as an ogc.geo.topo.features.topo-feature
  when its geometry is defined by reference/topology rather than embedded coordinates.
  heritage-object's CIDOC-CRM attributes nest under `properties` (GeoJSON convention);
  `properties.choType` carries the CIDOC-CRM class (Cultural Heritage Object type)
  as a second alias to `@type`, alongside the fixed `type: \"Feature\"` \u2014 the
  same secondary-typing pattern PROV-O's own prov-entity block uses for its `provType`
  property, kept as a distinct name here since this block has no PROV-O involvement."
