03Questions

Questions and answers.

Are these all the rules for developers and APIs?
They are the rules stated by the listed standards. The principles of NS-0 bind every standard; clauses specific to the area, where needed, are written under NS-10 and evaluated under NS-11.
What does a rule identifier such as NS1-R5 denote?
The number of the standard and the number of the rule within it. Rule identifiers are stable so that clauses, attestations and publications can cite them.
Standards

Shape the standards for developers and apis.

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.
