# Stage 4: model things and meaningful relationships

**Outcome:** a concept map and relationship ledger. **Time:** 1 to 2 hours.

## Explain and inspect

A stable identifier continues to name a thing when its display label changes.
A semantic relationship is a directed, evidenced statement such as “dataset
is published by organisation”. A clickable Markdown link is not automatically
a factual relationship. Similar labels do not prove identity. Use Explorer's
Reader, Links and Inspect views to read an existing relationship both ways.

## Do and check

Give each concept a short stable ID, preferred label, type and source. Add a
relationship only when it answers a competency question or materially improves
navigation. Record direction, labels, predicate, authority, derivation, time,
evidence and rights. Keep inferred, model-derived and synthetic assertions
distinct from official ones. Reject decorative or unsupported links and test
near-neighbour identities.

## Retrieve and reflect

Explain why “A is related to B” is usually too vague for reliable grounding.
Record one removed link and the evidence needed to restore it.
