Specification of NS-8
OPEN. Reference: registry/open-standards-stack.yaml#zenodo (rules).
Electrified and connected activity in the Nordic and Baltic region
The map frames the Nordic and Baltic region as an example geography for the subject of NS-8; the frame gives context and is not a statement of where the standards apply. Shown at first: night-time lights, daily (VIIRS Black Marble, VNP46A2, NASA LAADS DAAC) and population density, 2020 (Gridded Population of the World v4.11, NASA SEDAC, CIESIN, Columbia University). The layer drawer adds true colour (VIIRS NOAA-20 corrected reflectance). 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.
The interactive map needs JavaScript; the layer list and sources are below.

NS-8 among the standards.
Fig.The standards on which NS-8 builds, those that cite it and the programme areas where it applies, from the texts and the registry.
The standard as a process
A catalogued artifact is checked for rights and licence before deposit; its metadata are exported; the deposit is made; the DOI is written back to the record; software is archived with its persistent identifier. 6 operations in 5 phases; each states its actor, its decision rule, the record it leaves and the rule identifiers it implements (6 rules of NS-8 and the standards it applies). Records and artifacts are cited by UNI (Unique Nexus Identifier) and version.
All operations in order (6)
- 01
Catalogued artifact start · Record
Only a catalogued artifact can be deposited; its record is the source of every metadata field.
- Who
- the publisher of record
- Decision rule
- every record carries the required metadata (NS-1)
- Record
- the artifact record with rights, creators and locations
- Implements
- NS1-R4
- 02
Rights and licence gate · Rights
The licence and the rights of every part are confirmed before deposit; a missing decision stops the deposit with its reason.
- Who
- the publisher of record
- Decision rule
- nothing is deposited without a recorded rights decision; missing evidence refuses
- Record
- a recorded rights decision for publication
- Implements
- NS0-P12, NS1-R4
- 03
Export metadata step · Export
Creators, title, version, licence and related identifiers are exported in the archive's metadata format.
- Who
- the catalog
- Decision rule
- metadata come from the record, never retyped
- Record
- deposit metadata exported from the record
- Implements
- NS2-R3
- 04
Deposit step · Deposit
The deposit carries the UNI as an alternate identifier.
- Who
- the publisher of record
- Decision rule
- the deposit cites the UNI
- Record
- the deposit at the open archive
- Implements
- NS2-R1
- 05
DOI write-back record · Deposit
Citations give the UNI first and the DOI after it.
- Who
- the catalog
- Decision rule
- the DOI follows the UNI and never takes its place
- Record
- the DOI recorded on the artifact record
- Implements
- NS2-R5
- 06
Software archive end · Archive
Source code is archived with an intrinsic identifier recorded on the artifact record.
- Who
- the publisher of record
- Decision rule
- software artifacts are archived with their source revision
- Record
- the software archived with its persistent identifier
- Implements
- NS12-R1
Fig.Phases read left to right; each card names the operation, its actor and the record it leaves, and each edge label names the hand-over. Play, step or scrub; the detail panel gives the full text of the selected operation.

Rules for the publication workflow
Recorded in the open-standards stack pending the drafting of NS-8; a deposit is evidence of publication.
- Deposit only records whose legalState is APPROVED and whose rights.accessRight is open or embargoed; LEGAL_REVIEW_REQUIRED, RESTRICTED and PROHIBITED never leave the repository.
- Every deposit carries the UNI in keywords (nexus-uni:<uni>) and in the description, and the returned DOI is written back to the record as relatedIdentifiers[IsIdenticalTo, DOI].
- New versions use Zenodo's new-version flow under the same concept DOI; the UNI stays the same (NS1-R1).
- Publication on Zenodo is a publication act of the publisherRef institution, recorded as a decision of that institution.

How NS-8 is developed, and how to take part
NS-8 is developed in the open under NS-13 (the stages and gates of NS-13). Working groups draft, councils decide the reserved matters, and anyone may propose a change, comment, submit an implementation report, object or appeal, without membership or fee.
- Who decides what: the decision-rights matrix.
- The process: stages, gates, review windows and appeals.
- Open gateways and calls: how to propose, comment, join a working group or request activation.
- Develop a standard: the development track and the lifecycle of each standard.
- NS-13 in the canonical repository.
Relation to external standards
NS-8 relates to external standards by identifier, clause number and URL (NS14-R1), and directs the reader to the issuing body.

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.
