Anatomy

What is a PubID?

Every standards document identifier decomposes into structured, machine-readable components. The same meaning can be rendered as a human-readable string, a URN, or structured JSON.

ISO/IEC 17031-1:2020/Amd 1:2022

Publisher

The issuing organization — ISO, IEC, IEEE, NIST, BSI, etc. Joint publications list multiple publishers separated by slashes.

Copublisher

Jointly published with — a second publisher sharing responsibility. Written after the primary publisher, e.g. ISO/IEC, IEC/IEEE.

Stage

Where in its lifecycle — WD (Working Draft), CD (Committee Draft), DIS (Draft International Standard), FDIS (Final Draft). Encodes development progress directly in the identifier.

Number

The unique numeric ID — assigned by the publisher. May include sub-parts (800-53), letter suffixes (9001), or prefixed sections (JIS A 0001).

Year

Publication or revision year — typically separated by a colon (:2015) or hyphen (-2018 depending on publisher convention).

Supplement

Amendment or Corrigendum — a supplement identifier contains the base identifier. Amd 1:2023 wraps the base standard, adding its own number and year.

Language

Publication language — en (English), fr (French), ru (Russian), etc. Not all publishers include this.

How It Works

Three Steps

From free-form text to structured, machine-readable data — and back again.

Parse

Input any standards identifier string — the parser recognizes publisher-specific grammar rules.

ISO 9001:2015

→

Structure

Decompose into typed components: publisher, number, year, part, stage, and more.

publisher: ISO
number: 9001
year: 2015

→

Output

Render as formatted PubID, canonical URN, or structured JSON — no data loss.

Architecture

Identifier Composition

Identifiers compose through algebraic relationships — an amendment identifier contains a base identifier, a corrigendum wraps a published standard, and adoptions layer publisher identities.

ISO/IEC 17031-1:2020/Amd 1:2022

An amendment identifier wraps an international standard identifier — the amendment carries its own type, number, and year, while the base standard remains intact inside it.

Capabilities

Why PubID?

A single, interoperable identifier system for the entire standards ecosystem.

Machine-Readable

Parse any identifier into structured components — publisher, type, number, year, stage, and more. Transform free-form text into typed data that machines understand.

Round-Trip Fidelity

Parse and re-render to get identical output. No information is lost in the transformation.

Shared Metaschema

Each publisher defines their schema using a shared metaschema — not a one-size-fits-all format.
