In one sentence

PTPGE is the open specification of print: a vocabulary of 726 terms and 56 product templates with permanent URIs, and one computable identity per configured product — so that buyers, printers and AI agents mean the same thing by the same words.

In one paragraph

PTPGE (the Periodic Table of Print & Graphic Elements) is an open, vendor-neutral specification for describing a printed product before the job ticket. It has two parts: meaning — a vocabulary of 726 terms, 56 product templates and 35 variables, every one a permanent URI, in 12 languages — and identity: a complete configuration resolves to one fingerprint (ptpge-cfs/1) that any system computes the same way. Five document forms carry it between parties: a printer's vendor declaration, a maker's supplier catalogue, a request, a quote and a UCP manifest, each with a published JSON Schema. Reading is open with no key, over REST and MCP; the data is versioned by date and licensed CC BY 4.0. PTPGE is held by a non-profit association being formed in Oslo, so that no single company owns it.

Facts

Name: PTPGE — the open specification of print (long form: Periodic Table of Print & Graphic Elements). Status: Public Beta; data version 2026-10-11. Size: 726 terms · 56 product templates · 35 variables · 12 languages · 5 document schemas · 14 suppliers and 1 vendors in the registers. Licence: CC BY 4.0 (vocabulary, schemas, documents, this page). Held by: PTPGE, a non-profit association being formed in Oslo, Norway. Origin: Patrik Knutsson; identity method published as Technical Note No. 1, DOI 10.5281/zenodo.21451592. Reference implementation: Trykkverk (pilot printer). Also listed: the official MCP Registry (org.ptpge/mcp-server) and the Claude connector directory.

Documents

The five documents — two pages: how vendor declaration, supplier catalogue, request, quote and UCP manifest fit together, and the five rules (PDF, latest; dated copies stay beside it, e.g. 2026-10-11). Technical Note No. 1 — the identity method ptpge-cfs/1, on Zenodo. Schemas — the five JSON Schemas with every field explained. Changelog — every data release, by date. Deprecation policy — what «permanent URI» means in practice.

The mark

One rule: the mark names the specification, never a product or a company. Do not recolour it, do not set it inside another logo. «PTPGE» is written in capitals; «PTPGE.org®» is the registered figurative mark.
