NS-10: Policies and clauses (machine-readable obligations

NS-10 is a proposed Nexus Standard; the artifacts it governs are identified by UNIs (Unique Nexus Identifier). NS-10 makes obligations machine-readable. A clause is one obligation: whom it binds (contextual UNIs, NS-9), what shall hold (a predicate over records), how and by whom it is evaluated, what evidence satisfies it and what happens when it fails. A policy is an ordered, versioned set of clauses with an owner, an adoption decision and a conformance profile. Users define policies and clauses and bind them to their contexts; an implementation evaluates and enforces them. External obligations (legislation, regulation, sector standards, treaty commitments) are expressed as clauses that cite their source; the source text is never reproduced.

03Earth observation

Population, settlement and hazards in Latin America and the Caribbean

The map frames Latin America and the Caribbean as an example geography for the subject of NS-10; the frame gives context and is not a statement of where the standards apply. Shown at first: population density, 2020 (Gridded Population of the World v4.11, NASA SEDAC, CIESIN, Columbia University) and night-time lights, daily (VIIRS Black Marble, VNP46A2, NASA LAADS DAAC). The layer drawer adds flood water, 3-day composite (VIIRS Global Flood Product); active fires and thermal anomalies, last day (VIIRS NOAA-20 375 m, FIRMS); and 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.

05Process

The standard as a process

An obligation is identified at its source and written as a clause with modality, subjects, condition, evaluation, evidence and failure effect; clauses are composed into a policy and enter through a proposal; the policy is bound to contexts; evaluators with mandates evaluate each clause and the failure effect applies; conformance is a projection of attestations. 9 operations in 6 phases; each states its actor, its decision rule, the record it leaves and the rule identifiers it implements (12 rules of NS-10 and the standards it applies). Records and artifacts are cited by UNI (Unique Nexus Identifier) and version.

Attestation (result of an evaluation)ATNXS-NSF-AT-000911nexus-attestation.v1.json (NS-11)

Clauses and policies are catalogued like any artifact (NS-1): allocated by the owner's catalog, append-only and versioned, with legalState and claimCeiling. A clause is reusable across policies; a policy references clauses by UNI and version and gives each a weight (blocking, required, recommended, informative).

2

The clause

FieldContent
modalityOne of the machine tokens MUST, MUST_NOT, SHOULD, SHOULD_NOT and MAY, as defined in RFC 2119 and clarified by RFC 8174. In prose they correspond to the NS-4 verbal forms: MUST to "shall", SHOULD to "should", MAY to "may".
subjectsSelectors that resolve to contextual UNIs: explicit UNIs, scopes, categories, domains, sectors, jurisdictions and environments. A name is never a selector (NS0-P10).
conditionA predicate in a declared language (jsonlogic, cel, sql-view, rego, jsonschema) over named inputs, each a record kind (NS-3) or an artifact category with a selector and a time window. The predicate is data; an implementation evaluates it with an engine for that language and records which engine and version it used.
evaluationcontinuous (on every relevant record), on-record, scheduled or on-demand. The evaluatorRef is never the subject itself and shall hold the verifierMandate (NS0-P5).
evidenceThe evidence kinds that satisfy the clause (record refs recordUni@recordVersion, receipts, digests, signed attestations, observations, external reports, human decisions), the retention period and the publicity.
onFailurerecord, warn, degrade-claim (lower the subject's claim ceiling), refuse (block the action at the point of action), escalate (to a role or mandate, never to a named person) or revoke, with a grace period where the law permits.
derivedFromThe Nexus or external standard and clause that the obligation implements, cited by identifier and URL.
authorityThe issuer and the recorded decision that adopted the clause.
3

The policy

A policy names its owner, its clauses with their weights, what it applies to (appliesTo selectors), its conformance levels and reporting interval, the standards it derives from and the decision that adopted it. Conformance levels are a fixed vocabulary:

LevelMeaning
SELF_DECLAREDThe subject states conformance; no evaluation has run. Displayed as a claim.
VERIFIEDEvery blocking and required clause has a current PASS attestation from an evaluator with a mandate (NS-11).
ATTESTEDAs VERIFIED, with signed attestations and published evidence digests.
RECOGNIZEDAs ATTESTED, with a recorded decision of an authority entitled to recognise conformance. The authority, not the policy, confers recognition.

No level means "certified" or "compliant" in the legal sense unless the decision of the issuing authority says so in its own terms.

4

Define, bind, evaluate, enforce and report

  • Define. A user creates clauses and policies as catalogued artifacts (mint, edit, version, propose). Every edit is a version; proposals follow NS-13.
  • Bind. A policy is bound to contexts (NS-9): a system deployment, a programme instance, an operational environment, a tenant or a jurisdiction. A binding is a record with its own authority decision.
  • Evaluate. For each bound context, the implementation runs the evaluator for each clause in the declared mode, under the evaluator's own mandate, and writes attestations (NS-11). Evaluation never runs on the subject's own authority.
  • Enforce. refuse blocks the action at the point of action with a typed reason; degrade-claim lowers the context's claim ceiling; escalate opens a decision case (decision support class, DSS). Every outcome is visible on the surface where the action was attempted, with the clause UNI and the attestation UNI.
  • Report. Conformance per policy per context is a projection of attestations, never a stored verdict, and carries the evaluation timestamp and the evaluator.
5

Rules

RuleText
NS10-R1Every obligation that an implementation enforces shall be a clause with a UNI; code may implement a rule, but no rule shall be enforced without a clause record that names it.
NS10-R2Subjects shall be contextual UNIs; names, labels or free text shall not bind.
NS10-R3The predicate shall be data in a declared language; evaluators shall record the engine and its version; two conformant evaluators shall reach the same result for the same clause and the same inputs.
NS10-R4External obligations shall be cited, not copied.
NS10-R5Failure effects shall be typed; refuse is the default for blocking clauses in production contexts.
NS10-R6A clause or policy whose legalState is other than APPROVED may be evaluated, but its results shall be displayed as claims under review.
NS10-R7Policies and clauses shall be append-only artifacts: withdrawal and supersession keep the record.
6

Adoption by implementations

An implementation adopts this standard by providing: artifact types for clauses and policies; catalog allocation under each tenant's scopes; an evaluator whose mandates are issued by the implementation's trust authority (NS-11); surfaces for binding and for results; and a recorded policy decision as its adoption record. It reports its status in registry/consumers.yaml.

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.
