Twin Domain Kernel — framework-agnostic, zero-dep (domain + sim + 3-channel contract). WMS/YMS/MES, EPCIS 2.0 · ISA-95.

Map Digital Product Passport data to GS1 EPCIS 2.0 events, with a CBV 2.0 vocabulary extended for steel production steps. Pure functions, no third-party runtime dependencies.

Signing of EPCIS events in form of verifiable credentials for tracability and immutability

Javascript SDK for the EPCIS 2.0 standard

Operations domain contract — the standard vocabulary that producers and readers agree on (EPCIS 2.0/GS1, ISA-95, IEC 61850/ISO 50001). Types, guards, validation. No state, no engine.

Experimental prerelease: Versioned VSC draft compatibility profile with its proof suites and verification, the EPCIS source helpers with pinned EPCIS 2.0.1 artefacts, and the external ecdsa-rdfc-2019 credential verifier

n8n community node for TracePass — automate EU Digital Product Passport workflows: products, passports, EPCIS supply-chain events.

Model Context Protocol server for TracePass — the EU Digital Product Passport platform. Lets AI assistants manage products, passports, and EPCIS supply-chain events.

Library to convert EPCIS messages into JS

EPCIS 2.0 toolkit for engineers and agents: translate EPCIS 1.1/1.2 XML to 2.0 JSON-LD with per-job fidelity reports, validate against the pinned official GS1 EPCIS 2.0.1 schemas (sha256 pins), compute CBV 2.0 §8.9 event hashes, run a local capture gatewa

Validate EPCIS files with ease

Open-source Digital Product Passport renderer: a self-contained SPA that consumes signed DPP snapshots + EPCIS events and renders the public passport page for a publisher.

TypeScript SDK for EPCIS 2.0 and GS1 traceability applications

Record events for an item, events could be status updates, EPCIS events, location events etc . The events will be stored immutably.

Trawler library to parse CSV to EPCIS XML

Deterministic synthetic sample-passport and EPCIS-shaped event-chain generator for the OpenDPP Digital Product Passport API — category-valid ESPR sample data for every category the public contract recognises (ESM, Node >=26).

No description provided.

Verifiable without joining, runnable: verify EPCIS 2.0 event bundles against GS1's pinned official schema and the CBV 2.0 §8.9 event hash, render chain-of-custody traces from local event files, and print the checkable spec citations. Local-only — no netwo

The business-transaction layer for engineers and agents: parse X12 into lossless wire-canonical JSON, emit it back byte-exact, validate envelopes and the 856 HL hierarchy against self-authored sha256-pinned grammars, generate 997 acknowledgments, compile

Headless digital-twin host — operato-twin kernel(WMS/YMS/MES) 를 things-factory 모듈로 호스팅(State GraphQL subscription + 이벤트 영속 + 워커 tick + command/scenario mutation).
