title: Heritage Proposition Set
description: "HDTO's HC16 Heritage Proposition Set (\u2291 crminf:I4 Proposition Set
  + HC15 Persistent Digital\nObject): the named-graph content unit a `heritage-digital-twin`
  (HC2) actually \"contains\" via\nHP33/HP34. Per D7.1's own worked example (Figures
  16-17), a real HC16 instance is a\nprovenance-linked graph (digitization/study process
  \u2192 software/device \u2192 data output), not a\nflat metadata bag \u2014 modelling
  that full CRMdig process chain is deliberately deferred (see\n`description.md`);
  this schema covers the flat \"what does this set assert, and about what\" shape\nneeded
  to make HC2 usable now, with `content` as the extension point for deeper chains
  later.\n"
