Per the earlier correction to my typo, the DISCUSS was on the bearer spec. It asked me to reference syntax restrictions for scope and error values the core spec, that it turns out were not uniformly present there. The chairs decided to ask the working group whether to add them there (allowing me to satisfy the bearer DISCUSS) or whether not to (in which case, we'll have to come up with a different resolution).
I believe it was reasonable of the person filing the DISCUSS to expect the syntax for these elements to be the same between the two specs, and so reasonable of the chairs to ask the question. To my knowledge, there was no working group consensus that the syntax of these elements should be different across the OAuth specs (despite your apparent representation to the contrary below). In fact, at least in the case of the scope parameter, there was clear WG consensus tracked as http://trac.tools.ietf.org/wg/oauth/trac/ticket/27 to make them be the same. Yes, I have expressed my personal opinions as a member of the working group in appropriate contexts (as have you). But I have never represented my personal opinions as working group consensus unless that was actually the case, your statements below notwithstanding. -- Mike P.S. As you know, the other outstanding consensus call about registering OAuth Errors was a result of a DISCUSS on the bearer spec that explicitly asked us to register the bearer errors in the existing OAuth Errors Registry - not a result of me suggesting that that should occur or me failing to accurately represent the working group discussions on that issue to date. Again, it's a fair question raised by an IESG member, and one that Stephen Farrell asked the chairs to make a working group consensus call on, so that DISCUSS can be addressed as well. -----Original Message----- From: Eran Hammer [mailto:e...@hueniverse.com] Sent: Wednesday, May 09, 2012 4:05 PM To: Mike Jones; Hannes Tschofenig; oauth@ietf.org WG Subject: RE: [OAUTH-WG] Encoding of Errors in the Base and in the Bearer Spec There was no such discuss on the core specification. The only open discuss on the core specification related to character sets is to translate the EXISTING prose into ABNF which will not have any implementation impact. The proper response to the bearer specification discuss was to simply add a registry there, and to clearly state that this matter was discussed extensively by the WG and the design committee. Instead of representing this information to the IESG, you failed to do your job as editor and offered your personal view which was rejected by the WG and recorded in the issue tracker at the time. You don't get a second chance to insert your personal position during the IESG review process. As editor, you only get to represent the WG consensus when addressing issues. If you go and read my responses to the long list of discuss items on the core specification you will see that I represented views I personally did not agree with (the lack of interop, undefined security, etc.) because as editor, I don't get to go to the IESG and disrespect the WG's decision. The IESG members rely on the editor to represent the WG decisions to them when addressing issues. You failed to do that, promoted your personal view, and now we are having this discussion all over again - a discussion that last time was only resolved by creating the design committee.
