External Vocabularies

The UN/CEFACT Web Vocabulary deliberately coexists with the authoritative vocabularies of the web and of trade. Where an external vocabulary already owns a concept well, the Vocab reuses, references, imports or maps to it rather than reinventing it — and pins what it depends on.

This page is generated from the recognised-vocabulary register (schema) — a machine-readable list of every vocabulary the Vocab recognises, each of which must meet the well-governed vocabulary criteria.

Foundation

Normative mappings

The Vocab lives among overlapping authoritative vocabularies. Rather than redefine or defer, it maps: every term and code that overlaps a peer carries an explicit, maintained equivalence.

Mappings are tiered by fidelity:

  • Tier A, semantic (SKOS): skos:exactMatch / closeMatch / broadMatch / narrowMatch for 1:1 or near-1:1 correspondences. Carried in-band on the term itself. Where a correspondence crosses kinds (a Vocab role-property whose peer is a class, as with FIBO’s role classes), rdfs:seeAlso links it instead, without asserting concept equivalence.
  • Tier B, structural (SHACL / rules): where a concept maps but its shape differs (planned).

Where the mappings live

Tier-A mappings are in the TTL (each term’s skos:exactMatch/closeMatch), so they ship with the vocabulary and are queryable. The register above is the human-facing index; the machine-readable truth is the graph. The full provenance and validation trail is on the Governance page.


Dependency policy: external vocabularies are treated as peers, not dependencies — the versions above are pinned and mapped to a stable subset, so an upstream change never silently breaks the Vocab.
