Question 16 of 21 · Identification
Which scheme will you use for the identifier and URL?
Possible answers
- Own scheme on company domain
Addresses on your company domain, with a scheme you define.
- Self-issued / EN IEC 61406
Identification link under IEC 61406: a unique, stable web address on the manufacturer's domain.
E.g.https://id.company.com/MOD123/SN000123- ISO/IEC 15459 (ASC MH10)
Unique identifier under ISO/IEC 15459, with ASC MH10 data identifiers (e.g.
1P= part number), resolved by a web resolver.
E.g.https://resolver.org/1P/PART1234/S- Decentralized Identifiers (DID)
Decentralized identifiers (W3C standard) verifiable without a central authority.
E.g.did:web:id.company.com:products:MOD123- DOI (Digital Object Identifier)
Persistent identifier, born for publications and data, resolved through doi.org.
E.g.https://doi.org/10.1234/company.mod123- GS1 Digital Link
Standard that encodes the product code (GTIN) in a web address readable from a QR code.
https://id.brand.com/01/0401234567- I don't know
