The UNI and the artefact catalogue (grammar v0.2: domain, sector, region and environment segments)
Status proposed · trust, authorisation and assurance · NXS-STD-ST-000001.
| Rule | Text |
|---|---|
NS1-R1 | One UNI shall identify one artefact concept; versions share the UNI and differ in @VERSION. |
NS1-R2 | UNIs shall be allocated only through a catalogue (mint) or a record allocation authority (NS-3); they shall not be typed by hand. |
NS1-R3 | UNIs shall not be deleted or reused. A withdrawn artefact keeps its record (WITHDRAWN); a replaced one records supersededBy. |
NS1-R4 | Every record shall carry the required metadata; legalState defaults to review-required; claimCeiling stays inside the claim registry. |
NS1-R5 | The UNI shall be embedded in the artefact itself so that machines and people can find the record (section 6). |
NS1-R6 | A regional artefact shall carry REGION; public regional or national use still follows the geographic rules of the marks policy. |
NS1-R7 | Codes are classification and shall not be used as product names. |
NS1-R8 | A new scope, domain, sector or environment code shall meet the allocation rules CA-1 to CA-10 (section 1.1) and shall enter through an NS-13 proposal. |
NS1-R9 | A code shall not be reassigned or deleted; a retired code is deprecated with supersededBy, and identifiers that use it remain valid. |
NS1-R10 | A PROPOSED identifier may be used and shall be shown with its status until the registry change is adopted. |
Risk record UNIs (grammar, legacy crosswalk, allocation authority)
Status proposed · trust, authorisation and assurance; canonical risk data, records and provenance · NXS-STD-ST-000003.
NS-3 states its requirements in sections rather than in a table of rules.
Dataset and product metadata profile (STAC, DCAT, PROV-O)
Status proposed · trust, authorisation and assurance; canonical risk data, records and provenance · NXS-STD-SW-000005.
NS-3b states its requirements in sections rather than in a table of rules.
Verification and monitoring (evidence, attestations, zero-trust conformance observation)
Status proposed · trust, authorisation and assurance · NXS-STD-ST-000007.
| Rule | Text |
|---|---|
NS11-R1 | A conformance statement shall rest on an attestation, and an attestation shall name an evaluator, a mandate, evidence references and a digest. |
NS11-R2 | Under zero trust, subject and evaluator shall be distinct, and production evaluations shall run outside the subject’s trust boundary. |
NS11-R3 | Missing or unresolvable evidence shall yield INDETERMINATE or REFUSED, never PASS (NS0-P12). |
NS11-R4 | Attestations shall be append-only and superseded rather than changed; monitoring records shall be observations with record UNIs. |
NS11-R5 | Every displayed conformance value shall carry its evaluation instant and its evaluator; projections shall not store verdicts. |
NS11-R6 | Exports to Verifiable Credentials, in-toto or PROV-O are crosswalks; the Nexus attestation shall remain the record of truth. |
Conformance and crosswalk to external standards
Status proposed · trust, authorisation and assurance · NXS-STD-ST-000013.
| Rule | Text |
|---|---|
NS14-R1 | The text of an external standard shall not be reproduced; it shall be cited by identifier, clause number and URL. |
NS14-R2 | Relation claims shall come from the register and from clause sets, not from prose. |
NS14-R3 | "Compliant" and "certified" shall appear only as quotations of an authority decision cited by reference. |
NS14-R4 | Marks of standards bodies shall not form part of a Nexus name. |
NS14-R5 | Unverified register entries shall be displayed as unverified. |

Status and use. The Nexus Standards are proposed standards developed through an open process under NS-13 and published for voluntary use; they do not constitute certification, accreditation or regulatory approval, and adoption remains a decision of the Global Standards Council and, in each country, of its National Standards Council. A UNI (Unique Nexus Identifier) identifies an artefact; it does not certify it. Names of standards bodies and their standards belong to their stewards and are used only to identify the documents; no text of an external standard is reproduced here. Nexus Standards is not affiliated with, endorsed by or certified by any standards body named here.
