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

["Lars G. Svensson" <[e-mail]>]

Chris, all,

The registration of the gs1 namespace (version 6.1.0) is fine with me.

I have two minor suggestions that arised when I read _only_ the registration template (§ 2):
* It would be helpful to have links to the relevant ancillary documentation. 
* In the section "Identifier attribution semantics" it would be helpful to have some text clarifying the relation between GS1-Identifiers and EPC-Identifiers. My suggestion is something along the lines of
[[
URNs in the id branch of the gs1 namespace are related to URNs in the epc namespace [RFC5134] in that they can be used to convey product data including gtin, serial number etc. For a further discussion of this relation, please refer to §3.1 of <the enclosing I-D>.
]]
That would help to make the registration template work as a stand-alone document. If you choose not to make the changes, I'm fine with the document as-is, too.

Best,

Lars

Chris, thanks for the quick turnaround on these edits, and thanks to Dale for his reviews. I'll endeavor to send feedback soon.

However, it isn't stand-alone in one respect:  the Syntax section gives only an informal grammar, referring to the ABNF in Appendix A.  ISTM that the registration should contain the proper grammar.

E.g., given "urn:gs1:gdd:bie:TradeItem.netContent", is there text that states what document/text/concept this URN names?  This is opposed to there being a standardized table named "TradeItem" with an entry named "netContent" but no explicit text stating what the table entries imply about GS1 URNs.

It appears that <ai> URNs are semantically collections of attribute names and values.  It wouldn't be entirely surprising if explicitly specifying that fact (and exactly how collections are to be interpreted based on their members) might be overlooked during standards development.
