| **DISTINCTION FROM dcterms:identifier**: Use `has_code` (skos:notation) for classification codes and notations within a known scheme. Use dcterms:identifier for general unique identifiers like ISBNs, DOIs, URNs, and persistent URIs. - | **ONTOLOGY ALIGNMENT** (verified against data/ontology/): | Ontology | Property | Line | Mapping | Notes | |----------|----------|------|---------|-------| | SKOS | skos:notation | 166-175 | exact | Classification code notation | | DCTerms | dcterms:identifier | 1395-1418 | close | Unambiguous reference | | Schema.org | schema:identifier | 21325-346 | close | Any identifier for Thing | | CIDOC-CRM | crm:P1_is_identified_by | 1172-1187 | broad | General identification | | CIDOC-CRM | crm:P48_has_preferred_identifier | 2353-2369 | narrow | Preferred identifier | - Updated 2026-02-03 with verified ontology mappings and translations.
