Which standards apply
Which standards apply: routing console and composer
For a selected sector, hazard family, capability, jurisdiction and artifact type, the routing console identifies the corresponding programme areas of the registry, the Nexus Standards those areas list and the external standards in their domains, stating the reason for each; the composer turns the result into a draft profile that can be cited and downloaded. Each artifact carries a UNI (Unique Nexus Identifier).

All operations in order (7)
- 01
Context tags start · Adopter
The adopter selects a sector, a hazard family, a capability, a jurisdiction and an artifact type, each a controlled registry value.
- Who
- the adopter
- Decision rule
- tags are registry identifiers: sectors, hazard families, capabilities, categories and, where recorded, jurisdictions
- Record

- 02
Programme areas step · Routing engine
The same registry version gives the same result; each row states which programme matched.
- Who
- the engine, deterministically
- Decision rule
- sector, hazard and capability tags map to programmes by registry identifier
- Record
- the matching programmes
- 03
Nexus Standards step · Routing engine
Standards are listed with their status as recorded in the registry.
- Who
- the engine
- Decision rule
- the standards each programme lists, with status and rule count
- Record
- the standards the areas list
- 04
External entries step · Routing engine
External standards are named and linked; the relation is as recorded in the register.
- Who
- the engine
- Decision rule
- the entry's domain is a crosswalk domain of the programme
- Record
- register entries in the areas' domains
- 05
Relation and access filter gate · Routing engine
Each row states its reason: programme, domain, relation and access.
- Who
- the engine
- Decision rule
- adopt and profile first; paywalled crosswalk, profile and extend relations shown as compatibility profile (restricted)
- Record
- the filtered list with reasons
- 06
Profile draft record · Result
The composer turns the result into a profile draft for download.
- Who
- the adopter, from the result
- Decision rule
- a profile cites every source by identifier and clause; the licence line travels with it
- Record
- a profile as YAML and JSON with citations
- 07
Change proposal end · Nexus Standards editors
A change proposal is a pull request with the profile record; editors decide with written reasons.
- Who
- any person, with identity recorded
- Decision rule
- every submission is a change proposal under NS-13
- Record
- a change proposal with the profile record
Fig.Each selection lights the operation it feeds; the result keeps its reasons. Sources: Nexus Standards programme register · NS-14: crosswalk and conformance claims · NS-9: contextual UNI.
The routing is deterministic: the same registry version gives the same result, and each row states the area, domain and relation that routed it. Jurisdiction does not yet narrow the result, as the registry does not yet carry jurisdiction tags.
Hazards and exposure in South Asia
The map frames South Asia as an example geography for routing a question to the applicable standards; the frame gives context and is not a statement of where the standards apply. Shown at first: flood water, 3-day composite (VIIRS Global Flood Product, NASA LANCE); active fires and thermal anomalies, last day (VIIRS NOAA-20 375 m, FIRMS, NASA LANCE FIRMS); and population density, 2020 (Gridded Population of the World v4.11, NASA SEDAC, CIESIN, Columbia University). The layer drawer adds land surface temperature, day, 8-day composite (VIIRS NOAA-20 Level 3, 8-day); night-time lights, daily (VIIRS Black Marble, VNP46A2); and aerosol optical depth, daily (VIIRS NOAA-20 Deep Blue AOD). NASA products are served through NASA GIBS under NASA's open data policy, with acknowledgement; population density is GPW v4.11 by CIESIN, Columbia University, under CC BY 4.0; coastlines, boundaries and place names come from NASA GIBS reference layers (© OpenStreetMap contributors, ODbL) and Natural Earth (public domain). Each layer shows its own observation date; full credits are given under the map.

Registry files used by the console
| Registry file | Content used |
|---|---|
| registry/sectors.yaml | sectors and the programme area of each |
| registry/subsites.yaml | programme areas, the standards they list and their crosswalk domains |
| registry/external-standards.yaml | entries with body, version, relation, access and URL |
| standards/INDEX.md | status and rules of the Nexus Standards |
| registry/nexus-standards.yaml | artifact categories (the artifact type) |
Per-rule artifact tags are being added to the registry; until then, the artifact type adds the identification standards area.

Around the Nexus Standards.
Take part in the standards.
Governments, regulators, standards bodies, industry, academia and communities are invited to shape the catalogue ahead of its first official release, targeted for 2030: comment on a draft, propose a change, join a working group or host a field exercise.
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 artifact; 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.
Licences: CC BY 4.0 for standards text, registries, schemas and data; Apache-2.0 for reference code. External standards are cited by name, number and link under their own licences. Third-party data, libraries and fonts keep their own licences: see Third-party notices.
