Professional Passport

The Professional Passport is where the World Skills Protocol becomes something a person can hold: the append-only, professional-owned surface of their identity (Opus ID). Each accepted Evidence adds one Passport update; the professional controls disclosure through consent, but no one — not the professional, not the Issuer — can edit or delete the underlying facts.

Canonical Definition

A Professional Passport is the professional-facing, append-only surface of a professional's Opus ID within the World Skills Protocol, accumulating one Passport update per accepted Evidence, owned by the professional, disclosed under consent expressed as facts, and never permitting mutation or deletion of the underlying Immutable Facts.

Key Facts

  • The Passport is designed to surface bound facts coherently, to update deterministically (one update per accepted Evidence), to be owned and disclosure-controlled by the professional, and to remain verifiable by third parties.
  • The central tension is between control and integrity: the professional must control what is shown, yet must not be able to fabricate or erase what happened.
  • WSP resolves this by separating disclosure (controlled) from existence (immutable).
  • A second tension is between coherence and rawness: the Passport presents a coherent identity while the underlying facts remain individually verifiable.

Why It Exists

Immutable facts and computed trust are necessary but not sufficient: a professional needs a coherent surface to hold and present, and a verifier needs a stable object to check. The Passport exists to be that surface without reintroducing the failures WSP eliminates. It must not become an editable résumé (which would let people curate away inconvenient truth) nor an issuer-owned artifact (which would strip the professional of control). By making the Passport an append-only accumulation of Passport updates, owned by the professional and disclosed under consent, WSP gives a human-usable identity that preserves immutability and portability.

How It Works

A Passport comprises the professional's Opus ID reference, the ordered accumulation of Passport updates (each linked to exactly one accepted Evidence), the current disclosure state derived from consent facts, and the trust surface computed over the bound facts.

It does not comprise editable fields, deletable entries, or issuer-owned sections. The relations: an accepted Evidence produces a Passport update; the update belongs_to an Opus ID; the professional owns the Passport and governs disclosure; Trust is surfaced by the Passport. No relation lets the holder or an Issuer mutate a bound fact.

Actors

A Passport surfaces an Opus ID (OCR-104). It accumulates Passport updates, each linked_to one accepted Evidence / Immutable Fact (OCR-110/OCR-114). It surfaces Trust (OCR-105) and Trust Status (OCR-106). It is checked_by Verification (OCR-107). It belongs_to a Professional (OCR-103). It is part_of the World Skills Protocol (OCR-100).

Lifecycle

  1. 01Establishment — a Passport is established for a professional's Opus ID.
  2. 02Update — each accepted Evidence produces exactly one Passport update (uniquely linked).
  3. 03Accumulation — updates accumulate append-only over time.
  4. 04Disclosure — the professional governs what is shown via consent facts.
  5. 05Presentation & Verification — a verifier checks disclosed, surfaced facts independently.
  6. 06Supersession/Revocation reflection — when a fact is superseded or revoked, the Passport reflects the change without deleting history.

Examples

  • ·A professional's Passport shows a trust surface computed from bound Evidence; each entry traces to one accepted Evidence via a unique Passport update.
  • ·The professional withholds a specific item; it disappears from disclosure but remains stored and can be re-disclosed later.
  • ·An Evidence is revoked; the Passport reflects the revocation without deleting the entry.

Counter Examples

  • ×An editable résumé the professional curates — a Passport is append-only and not curated.
  • ×An issuer-owned profile page — the Passport is owned by the professional.
  • ×A trust score typed into the Passport — trust is surfaced, computed, not authored.
  • ×Two Passport entries from one Evidence — refused by UNIQUE.

Distinctions

The Passport is often confused with the identity itself; the identity is Opus ID, the Passport is its surface. It is assumed editable like a CV; it is append-only. It is assumed issuer-owned; it is owned by the professional. It is assumed that withholding deletes; it only hides.
