Registration Request: [ Digital Product Passport ]
Relation Name
dpp
Description
A link to a digital product passport.
Reference
https://ref.gs1.org/voc/dpp
Additional Information
The term Digital Product Passport was coined by the European Commission in their Ecodesign for Sustainable Products Regulation but is gaining traction as a more general term. Notably this is true within the UN Transparency Protocol being developed at UN/CEFACT. The UNTP approach is consistent with ISO/IEC 18975. It is further consistent with, but does not depend on, GS1 standards GS1 Digital Link URI Syntax and GS1-Conformant resolver. The UN/CEFACT and GS1 standards refer normatively to RFC 9264 Linkset: Media Types and a Link Relation Type for Link Sets as a means to connect a single URI to multiple sources of information about the identified resource. One likely such piece of related information will be a product's digital passport.
Specific references to the concept of link (relation) types appear in the following standards:
- UNTP Identity Resolver, see bullet 4 within the Conceptual Model section
- See section 2.5.2 of the GS1-Conformant resolver standard
The definition of the link relation type provided by the GS1 Web Vocabulary A link to a digital product passport is extremely simple so as not to limit its use to a specific definition of a DPP or access protocol.
Almost as an aside, GS1 maintains a list of "link types" within its namespace. It is anticipated that, in future, more of those, perhaps all, will be submitted to IANA for consideration as new link relation types so that they can be used as tokens and not as URIs. For now, however, this is a specific request to add dpp as a new link relation.
Phil, please see the registration requirements https://datatracker.ietf.org/doc/html/rfc5988#section-6.2.1 and augment the request accordingly.
Hi Phil,
I like this idea because it allows for showing a DPP for products that are already serialized using GS1 coding standards without the need to apply a new or additional code on the product.

Happy to provide whatever it is I've missed, Jan, of course, but I can't see exactly what that is, sorry. Let me try again:
- Relation name: dpp
- Description: A link to a digital product passport
- Reference: several given. The actual term is defined within the GS1 Web Vocabulary (managed and published as a GS1 standard under our Global Standards Management Process) but I also provided references from related standards at ISO/IEC, GS1 and UN/CEFACT. I am aware that ISO/IEC standards are useless in this regard as they're behind a paywall but the GS1 and UN/CEFACT standards are fully open and, in some communities, the ISO/IEC reference adds credibility.
- Notes - extensive notes provided.
Phil,
In the description, pls if possible describe the relationship of the target resource to the context.
Also, pls provide exactly what should be stated as Reference.
And if Notes: should be filled, pls provide the Notes exactly as they should be stated.
Jan
Thanks @algermissen. OK, let's try this:
- Relation: name: dpp
- Description: A link from a context URI that identifies a product to its digital product passport
- Reference: UN Transparency Protocol
- Notes: Equivalent to https://ref.gs1.org/voc/dpp
