GRAI regex wrong

[JohannesFluegel]

I don't know if your GRAI regex (\d{14})([\x21-\x22\x25-\x2F\x30-\x39\x41-\x5A\x5F\x61-\x7A]{0,16}) might be wrong. It means 14 digits then 0 to 16 special chars. But in https://www.gs1.org/docs/Digital-Link/GS1_Digital_link_Standard_i1.1.pdf, page 21 we read

grai-value = 14DIGIT 1*16XCHAR
; 14 digits then 1-16 characters
; from the 82-character subset of ISO/IEC 646

Hi @JohannesFluegel
Thanks for the feedback. This was one of the things recently fixed in an errata fix to the published GS1 Digital Link v1.2 URI Syntax https://www.gs1.org/docs/Digital-Link/GS1_Digital_Link_Standard_URI_Syntax_r_i1-2-1_2022-02-08.pdf where on page 19 you'll now see

grai-value = 14DIGIT [1*16XCHAR]
; 14 digits then optional 1-16 characters
; from the 82-character subset of ISO/IEC 646

towards the end of section 4.5.

Please refer to GS1 Digital Link v1.2 URI Syntax for all current ABNF grammar.

Tagging @philarcher - should the recent errata fixes from 2022 also be applied to the GS1 Digital Link v1.1 standard in case anyone is still referring to it?

Thanks @JohannesFluegel for raising this and @mgh128 for answering so promptly.

I don't think DL version 1.1 needs updating as such. The currently published URI Syntax version 1.2.1 supersedes the equivalent sections in 1.1, which is where these errata have been corrected. Sure, we do want to update the remainder of 1.1 but, in terms of published normative statements, the primacy of URI Syntax version 1.2.1 is, I hope, clear.
