Nexus Standards · Resources
For experts and developers
Resources and tooling
The registry, the schemas, the record catalog, the reference command-line tool, snippets for parsing a UNI (Unique Nexus Identifier) in five languages and the export crosswalks. Each file links to its path in the canonical repository; files in preparation are marked planned. Repository revision 52ade713b78a.
The process.
NXS-STD-ST-000001NXS-EWS-DS-KEN-000003NXS-GRX-RP-M002-000007@1.2.0NXS-GRX-OB-KEN-000042@3NXS-GCR-AR-000015Illustrative identifier pattern. With script enabled, a UNI can be entered and each segment is checked against the registry, resolved to its record where one is published, and expressed as a URN, a resolver link and a citation.
UNI anatomyThe NS-1 grammar segment by segment, with the scope and category codes of the registry. Resolution links to the resolver; no identifier is allocated on this page.
Machine-readable registry
YAML is the authoritative form; JSON projections are served by the resolver service and are planned as repository exports.

The land surface from orbit in the Nordic and Baltic region
The map frames the Nordic and Baltic region as an example geography for the tooling of the standards; the frame gives context and is not a statement of where the standards apply. Shown at first: true colour (VIIRS NOAA-20 corrected reflectance, NASA LANCE). The layer drawer adds land cover type (IGBP), yearly (MODIS Terra and Aqua land cover, MCD12Q1); enhanced vegetation index, rolling 8 days (MODIS Terra EVI); snow cover (VIIRS NOAA-20 NDSI); and sea ice concentration (GHRSST MUR). NASA products are served through NASA GIBS under NASA's open data policy, with acknowledgement; 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.
The interactive map needs JavaScript; the layer list and sources are below.

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.
