Identity Resolvers
Please note that this content is under development and is not ready for implementation. This status message will be updated as content development progresses.
Overview
Identifiers of businesses (e.g., tax registration numbers), of locations (e.g., Google pins, property identification codes), and of products are ubiquitous throughout supply chains and underpin the integrity of the system.
UNTTP Textiles Extension builds upon existing identifier schemes without precluding the use of new schemes so that existing investments and high integrity registers can be leveraged. UNTTP requires four key features of the identifiers and, for those that don't already embody these features, provides a framework to uplift the identifier scheme to meet UNTTP requirements. Identifiers used in UNTTP implementations MUST be:
- discoverable (quoted in exchanged documents and, when attached to products, easily read by scanning a barcode, QR code, or RFID),
- globally unique (by adding a domain prefix to local schemes),
and SHOULD be:
- resolvable (given an identifier, there is a standard way to find more data about the identified thing), and
- verifiable (ownership of the identifier can be verified so that actors cannot make claims about identifiers they don't own).
For comprehensive guidance on how different identifier schemes work together in textile supply chains, see the Mixed Identifier Schemes use case page.
Identifier Scheme Register
The UN will maintain an identifier scheme register with specific meta-data about each register as described in the UNTP Identity Resolver specification. The UN register will provide verifiers in other regions with easy reference for key identifier scheme metadata. It will also act as a global whitelist for trusted registrar identifiers (DID). Once established, the scheme meta-data below will be replaced with references to the UN register.
Most identifier schemes that are important to UNTTP Textiles Extension are not yet ready to act as linked data signposts to verifiable data. For UNTTP implementers, the first step is just to ensure consistency in the population of URI identifiers of schemes and members. When referencing any of the schemes relevant to textiles in UNTTP credentials, use the following mapping:
Identifier scheme mappings will be documented here as they are developed and tested through working groups and pilot programs.
Digital Identity Readiness
Guidance on digital identity readiness for textile supply chain identifiers will be provided here as the extension is developed. This will include:
- Requirements for identifier schemes to support UNTTP
- Migration paths for existing identifier systems
- Best practices for implementing resolvable identifiers
