Hi Kai, all,

These RFCs are referring to Unicode in general, where several hyphens are 
supported.

RFC7285 points explicitly to US-ASCII alphanumeric characters, where U+002D is 
the only hyphen:
* There is no ambiguity about the intended behavior given that U+002D is 
provided
* Even if we reason about labels, there is also not ambiguity which hyphen is 
about

I don’t think there is an issue with RFC7285, but I would not object to an ** 
editorial ** errata.

That’s said, I’m for consistent use of labels and can fix this for the 
cost-mode I-D: 
https://github.com/boucadair/alto-cost-mode/blob/main/draft-ietf-alto-cost-mode.txt

Cheers,
Med

Hi Qin, Qiao and all,



I searched for a few documents and it seems that many documents are referring 
to U+002D as hyphen-minus. It seems to me that we should use hyphen-minus.

Best,

Kai

Hi, Kai and Qiao:
Is there any other RFCs which describe “hyphen” usages besides RFC7285?
Since this work is targeted to update RFC7285, there is a time window to 
improve RFC7285,
If “hyphen-minus” described in https://www.unicode.org/charts/PDF/U0000.pdf, is 
current best practice, I have no better reason to reject this request,:-)
The price is we should also update other sections related to cost metric and 
global endpoint properties with “hyphen” usage.

Hi Qiao and all,



Thanks for reviewing the document.



In RFC 7285, "hyphen" is used when defining PID, cost metric, etc. One option 
is to use the term consistently with existing RFCs.



Best,

Kai

Hi Kai and all,

I have read the document and support the proceeding of its publication with one 
tiny suggested edit:

Section 3.2: the hyphen ('-', U+002D) -> the hyphen-minus ('-', U+002D)

This is to be consistent with the official name of this character in 
https://www.unicode.org/charts/PDF/U0000.pdf.


Best
Qiao

Hi all,

As discussed during the ALTO session in IETF 113, the ALTO cost mode document 
is now adopted as a working group document. A new WG version 
(draft-ietf-alto-cost-mode-00) [1] has been submitted to replace the individual 
draft and address comments from the Call for Adoption.

To move forward, this message starts the WGLC for draft-ietf-alto-cost-mode-00. 
The WGLC will run till April 8, 2022 (two weeks from now).

As both WG chairs are co-authoring the document, I’m taking care of this call 
as part of my document shepherding. We would like to have 2-3 reviewers from 
the working group. Please review and indicate your support or objection to 
proceed with the publication of this document.

Thanks!

Best,
Kai
