[urn] Re: GS1 URN: submission, version 6.1.0

[Chris Day <[e-mail]>]

Hi Peter –

Sorry for the delay. I’ve attached a reformatted request in RFC 8141 format for your review. We can treat this as Version 1, and I’ll get on with the RFC for the Independent Submissions Stream process.

Hello again.

Chris, I notice that your registration request to the URN list took the
form of an Internet-Draft, which included much more information than
simply the completed registration template. Although I do not want to
remove any information that would enable readers to understand the
namespace (e.g, the Appendices), it's unclear to me how to reformat the
registration request at this time for consistency with RFC 8141 and all
the other formal namespace registrations.

Do you plan to eventually publish an RFC (likely through the Independent
Submissions Stream) containing the more complete information? If so, we
could treat version 1 of the registration (i.e., only Section 2 of the
document you sent to the list) as something of a placeholder so that GS1
can move forward with its standardization process, then include version
2 of the completed registration template with the RFC.

Please advise as to your preferences.

Peter
