Land and soil risk: crosswalk to external standards
The external standards in the crosswalk domains of land and soil risk, from the register, with the relation of each to the Nexus Standards. Each row links to the issuing body, and each relation is evidenced by attestations identified by UNIs (Unique Nexus Identifier).
- Nexus Standards: NS-0, NS-1, NS-3, NS-3b, NS-5, NS-9, NS-11.
- Open standards: SpatioTemporal Asset Catalog (STAC); OGC API – Features; System of Environmental-Economic Accounting – Ecosystem Accounting; FAIR Guiding Principles; CARE Principles for Indigenous Data Governance.
- Data and feeds: SoilGrids 2.0 global soil property maps; ESA WorldCover 10 m land cover; Copernicus Land Monitoring Service products; Global Forest Watch tree cover loss (Hansen/UMD) and alerts.
- Couples with: Food and agriculture; Water; Geophysical hazard; Biodiversity and nature.

Relation types and their evidence
| Relation | Meaning | Evidence |
|---|---|---|
cite | The Nexus Standard refers to the external standard as context. | Identifier, version and URL in the register. |
profile | The Nexus Standard constrains or specialises an open external standard (for example STAC, DCAT, PROV-O, DataCite, CAP). | Conformance tests against the external standard’s own validator where one exists. |
crosswalk | Elements of the external standard map to Nexus elements (clauses, record fields). | A crosswalk table in the register entry; each row cites the external clause by number, never by text. |
adopt | The Nexus Standards use the external standard as it is for a function (for example ISO 3166-1, SPDX, ORCID, ROR). | Validation of values against the external scheme. |
extend | A Nexus Standard adds machine-readable, real-time or provenance elements that the external standard lacks. | The extension is a Nexus clause or field; the external standard is cited as the baseline. |
gap | No external standard covers the concern; a Nexus Standard specifies it. | The gap statement in the landscape study. |
Questions and answers.
Does a crosswalk establish that a land and soil risk artefact conforms to these standards?
Why are some relations shown as compatibility profile (restricted)?
Why are some entries marked unverified?
Around land and soil risk.
Shape the standards for land and soil risk.
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 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.
