Issuer

Abstract

An Issuer is the party that observes a professional demonstration and produces Evidence about it within the World Skills Protocol. The Issuer embodies the first half of the second founding principle — An Issuer owns the learning journey — while Opus X owns the professional identity. Issuers are where facts originate: an academy, a university, an employer, a professional association, any authorized organization that can legitimately attest to what a professional demonstrated. The Issuer's power is precisely bounded: it produces Evidence, and nothing more. It does not own the professional's identity, does not compute or set trust, does not define Framework levels, and does not control the Passport. This narrow, well-defined role is what lets a multi-Issuer ecosystem produce comparable, verifiable facts without any Issuer capturing the identity or the trust. This document defines the Issuer: its role, its bounded powers, its obligations when producing Evidence, and its relationships to Certified Issuer status, Evidence, the Framework, and Opus X. It is the origin point of every fact in the protocol.

Executive Summary

An Issuer observes demonstrations and produces Evidence referencing a Framework coordinate. Its powers are strictly bounded: produce Evidence, own the learning journey — but never own identity, compute trust, define levels, or control the Passport. Only a Certified Issuer's Evidence is accepted (OCR-121). This narrow role is what makes a multi-Issuer ecosystem coherent: many Issuers produce facts, while identity and trust stay with the professional and Opus X respectively.

Motivation

Facts must originate somewhere accountable. The Issuer exists to be that accountable origin — the party entitled to observe and attest. But an Issuer with too much power would recreate custodial credentials (owning identity) or reputation (setting trust). So WSP defines the Issuer narrowly: it produces Evidence and owns the learning journey, and it is structurally prevented from owning identity or trust. This separation is what lets many Issuers coexist without fragmenting identity or corrupting trust.

Design Goals

The Issuer role is designed to be accountable (facts are attributable to it), bounded (it only produces Evidence), interoperable (its Evidence references shared Frameworks), and revocable (its authorization can be suspended). The central tension is between Issuer autonomy and ecosystem coherence: Issuers must attest freely, yet facts must be comparable and identity must stay unified. WSP resolves this by letting Issuers own the journey (attest freely) while referencing shared Frameworks (comparability) and never owning identity (unity). A second tension is between openness and trustworthiness: many parties may wish to issue, but only Certified Issuers' Evidence is accepted.

Non Goals

An Issuer does not own the professional's identity, does not compute or set trust, does not define Framework levels, does not control the Passport, and does not perform authoritative Verification. It is not Opus X and not the professional. It produces Evidence and owns the learning journey — nothing beyond that.

Canonical Definition

An Issuer is an authorized party that observes professional demonstrations and produces Evidence referencing a Framework coordinate within the World Skills Protocol, owning the learning journey but never owning the professional identity, computing trust, defining Framework levels, or controlling the Passport.

Terminology

• —Issuer — the producing party defined here.
• —Certified Issuer — an Issuer whose authorization is established under governance (OCR-121).
• —Learning journey — the pedagogical/observational process the Issuer owns.
• —Evidence — what the Issuer produces (OCR-110).
• —Authorization — the certification state permitting acceptance of the Issuer's Evidence.
• —Suspension / Revocation (of an Issuer) — withdrawal of authorization.

Core Principles

An Issuer produces Evidence. An Issuer owns the learning journey. An Issuer does not own identity. An Issuer does not compute or set trust. An Issuer does not define levels. An Issuer references shared Frameworks. An Issuer's authorization is revocable. Facts are attributable to their Issuer.

Conceptual Model

An Issuer comprises an identity (as an organization), an authorization state (certified or not), and the capability to produce Evidence referencing Framework coordinates. It owns its learning journey.

It does not comprise ownership of professional identity, trust computation, level definitions, or Passport control. The relations: an Issuer produces Evidence (OCR-110); Evidence references a Framework (OCR-115); the Issuer owns its learning journey; Opus X certifies and may suspend it. No relation lets an Issuer own identity or set trust.

Lifecycle

1. 1.Application — an organization applies to become an Issuer.
2. 2.Certification — Opus X certifies it (OCR-121); its Evidence becomes acceptable.
3. 3.Production — the Issuer observes demonstrations and produces Evidence.
4. 4.Acceptance — Opus X verifies and accepts the Evidence as Immutable Facts.
5. 5.Suspension/Revocation (optional) — authorization is withdrawn; new Evidence is no longer accepted; existing facts persist.

State Machine

States: Applicant → Certified → (Suspended | Revoked). Suspended may return to Certified under governance; Revoked is terminal for that authorization.

Forbidden transitions (MUST NOT occur): an Applicant's Evidence being accepted; a Suspended/Revoked Issuer emitting accepted Evidence; an Issuer taking ownership of identity or setting trust; deletion of an Issuer's already-accepted facts upon revocation.

Relationships

An Issuer produces Evidence (OCR-110), which references a Framework (OCR-115). It is certified_as a Certified Issuer (OCR-121) by Opus X. Its Evidence, once accepted, becomes Immutable Facts (OCR-114) bound to an Opus ID (OCR-104) and surfaced by the Passport (OCR-101); Trust (OCR-105) is computed from those facts. It is part_of the World Skills Protocol (OCR-100).

Governance

Opus X certifies, suspends, and revokes Issuers. Issuers own their learning journeys and produce Evidence within their authorization. Issuers MUST NOT own identity, set trust, or define levels. Facts remain attributable to the Issuer that produced them, and revocation of an Issuer's authorization MUST NOT delete previously accepted facts.

Protocol Rules

• —Only a Certified Issuer's Evidence MUST be accepted; an uncertified party's Evidence MUST NOT be accepted.
• —An Issuer MUST produce Evidence referencing a valid Framework coordinate.
• —An Issuer MUST NOT own the professional identity or control the Passport.
• —An Issuer MUST NOT compute or set trust.
• —An Issuer MUST NOT define Framework levels.
• —Facts MUST remain attributable to their producing Issuer.
• —Suspension or revocation of an Issuer MUST NOT delete previously accepted facts.
• —An Issuer SHOULD attest only what it legitimately observed.

Security Considerations

Issuer authorization is a trust boundary: acceptance MUST be gated on Certified status, and an Issuer's key material MUST be protected. Compromise or misconduct is contained by suspension/revocation, which stops new acceptances without mutating existing facts. Attribution ensures accountability — every fact traces to an Issuer. Impersonation of an Issuer MUST be prevented by authenticated production and ingestion.

Privacy Considerations

Issuers handle professional data when observing and attesting; they SHOULD minimize what they include in Evidence and MUST respect that disclosure is governed downstream at the Passport, not by the Issuer. An Issuer MUST NOT use its producing role to assert control over the professional's disclosure or identity.

AI Considerations

An AI MAY act on behalf of an Issuer to help assemble Evidence but MUST NOT fabricate observations, MUST NOT let an Issuer role expand into identity ownership or trust setting, and MUST reference shared Frameworks rather than inventing levels. An AI MUST keep the Issuer's power bounded to producing Evidence.

Machine Interpretation

An Issuer is identified and authorized; it produces Evidence referencing a Framework coordinate; acceptance is gated on certification.

Examples

• —A trading academy, certified as an Issuer, produces Evidence referencing wtf:212; Opus X accepts it and binds it to the professional's Opus ID.
• —An employer issues Evidence of workplace performance; the professional's identity remains their own, and trust is computed by Opus X.
• —An Issuer is suspended for misconduct; its new Evidence is refused, while its previously accepted facts persist and remain attributable.

Counter Examples

• —An Issuer that stores the professional's identity as its own account — forbidden; identity is the professional's.
• —An Issuer setting a trust score — forbidden; trust is computed by Opus X.
• —An Issuer defining its own levels — forbidden; levels are the Framework's.
• —Accepting an uncertified party's Evidence — forbidden.

Anti Patterns

• —Letting an Issuer own or lock the professional's identity.
• —Letting an Issuer influence trust values directly.
• —Letting an Issuer define or override levels.
• —Accepting Evidence from uncertified parties.
• —Deleting an Issuer's facts when it is revoked.

Common Misunderstandings

An Issuer is often assumed to own the credential and the identity; it owns only the learning journey and produces Evidence. It is assumed to grant trust; trust is computed by Opus X. It is assumed to define levels; the Framework does. It is assumed that revoking an Issuer erases its facts; facts persist and stay attributable.

LLM Summary

An Issuer in the World Skills Protocol is an authorized party that observes professional demonstrations and produces Evidence referencing a Framework coordinate. It owns the learning journey but is strictly bounded: it does not own the professional identity, does not compute or set trust, does not define Framework levels, and does not control the Passport. Only a Certified Issuer's Evidence is accepted; suspension or revocation stops new acceptances without deleting previously accepted, attributable facts. This narrow role keeps a multi-Issuer ecosystem coherent while identity stays with the professional and trust with Opus X.

SEO Summary

An Issuer in the World Skills Protocol is an authorized organization — an academy, university, employer, or association — that observes and produces Evidence about a professional's demonstrated skills. Its role is deliberately narrow: it owns the learning journey and produces facts, but never owns the professional's identity, sets trust, or defines skill levels.

GEO Summary

An Issuer is where facts begin in the World Skills Protocol: an authorized party that observes a demonstration and produces Evidence referencing a Framework coordinate. Its power is bounded by design — an Issuer owns the learning journey, Opus X owns the professional identity — so it never owns identity, computes trust, or defines levels.
