description: 'GS1 (GS1 AISBL) is the not-for-profit, neutral standards body headquartered at Avenue Louise 523, 1050 Brussels,
  Belgium, that maintains the identification keys and data standards the rest of the supply chain hangs its transactions on
  — GTIN, GLN, SSCC, GINC and GSIN, the barcode and EPC/RFID capture standards, EPCIS and the Core Business Vocabulary for
  supply chain visibility events, GS1 Digital Link, and EANCOM, GS1''s own subset of UN/EDIFACT. GS1 does not run a commercial
  logistics service; it sits underneath every party in the chain, defining the identifiers a shipper, forwarder, carrier,
  terminal, customs authority and last-mile network all quote at each other. Its API posture is unusually open for a standards
  body: the full standards library is downloadable free as PDF from ref.gs1.org with no login, EPCIS 2.0.1 ships a normative
  OpenAPI 3.0.3 REST binding plus JSON Schema, XSD, WSDL, SHACL and JSON-LD ontologies, and GS1 AISBL itself operates a live,
  unauthenticated GS1-Conformant Resolver at id.gs1.org. What is gated is the other half — issuing GS1 identifiers and querying
  the Verified by GS1 registry are federated to national GS1 Member Organisations and sold under paid membership or a commercial
  API subscription, not offered self-serve by the Global Office.'

  description: 'The normative REST binding of the GS1 EPCIS 2.0 standard — the sector''s supply chain visibility event interface,
    describing what happened to an object, when, where and why, using Core Business Vocabulary terms. GS1 publishes the contract
    (OpenAPI 3.0.3, 29 paths) rather than hosting a repository: capture (POST /capture), query (GET /events plus resource-scoped
    views by epc, bizStep, bizLocation, readPoint, disposition and eventType), named queries (POST /queries), and mandatory
    webhook subscriptions (POST /queries/{queryName}/subscriptions) where the client supplies a `dest` callback URL and a
    signatureToken the server echoes back in a GS1-Signature header. Implementers host their own base URL; the specification
    declares no `servers` block.'

  name: GS1 Digital Link Resolver (id.gs1.org)
  description: GS1 AISBL's own live, unauthenticated GS1-Conformant Resolver, implementing the GS1-Conformant Resolver Standard
    1.2.0. It takes a GS1 Digital Link URI built from a GS1 identification key and returns either a 303 redirect to the brand
    owner's target resource or, on request, an RFC 9264 linkset enumerating every registered link type for that key. The resolver
    description document at /.well-known/gs1resolver declares the supported primary keys — 00 (SSCC), 01 (GTIN), 253 (GDTI),
    255 (GCN), 401 (GINC), 402 (GSIN), 414/415/417 (GLN), 8003 (GRAI), 8004 (GIAI), 8006 (ITIP), 8010 (CPID), 8013 (GMN) and
    8017/8018 (GSRN) — which includes the consignment and shipment keys logistics parties actually quote. No key, no signup
    and no contract is required to call it.
