+### National and maritime coverage contracts
+
+Belgium-wide and maritime reference Datasets use the same Dataset and
+VectorFeature entities as every other vector source. No parallel national
+schema is introduced.
+
+Required source metadata includes:
+
+```yaml
+authority_level: authoritative|official_context|contextual
+coverage_zones:
+  - belgium|flanders|wallonia|brussels
+  - belgian_north_sea|territorial_sea|exclusive_economic_zone|continental_shelf
+source_url: https://...
+attribution: text
+license_note: text
+reference_layer_name: normalized_layer_key
+```
+
+EEZ and continental-shelf records may have equal horizontal geometry while
+their `legal_domain` differs. They must remain distinct records. A selected
+bbox crossing regions or the coast produces zone-specific coverage items;
+only metrics with compatible source meaning, unit, time and method may be
+merged.
