title: Digital Representation Feature
description: "Feature-envelope wrapper for ogc.heritage.digital-representation: a
  spatially located digital asset 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.
  PROV-O's prov-entity (id, provType, wasAttributedTo, wasGeneratedBy, wasDerivedFrom,
  ...) is inherited flat at the top level, since prov-entity does not fix `type` to
  a specific class the way ogc.heritage.heritage-object does; digital-representation's
  own additions (isAbout, mediaType, persistentIdentifier, url) nest under `properties`,
  per GeoJSON convention. Like digital-representation itself, this block asserts no
  fixed CIDOC-CRM class of its own \u2014 `properties.choType` is required but left
  open (no `const`) for concrete profiles (e.g. ogc.heritage.survey-dataset) to pin
  to their own class, the same way digital-representation's other profiles (digital-surrogate,
  oral-history, derived-survey-product) each pin their own `type`."
