Hello ACE,I have just submitted a new version of draft-ietf-ace-key-groupcomm-oscore [0]. Besides clarifications and an overall editorial revision, this version includes the two main following updates.
1. I have implemented the new section and content reordering sketched by Göran (thanks!) in [1], with a couple of deviations from it agreed offline. This was requested during WGLC [2], together with three minor comments.
I have also addressed those minor comments except for a change in terminology ("Joining Request/Response" to "Join Request/Response"), which has to happen first in draft-ietf-ace-key-groupcomm [3]. Due to the ongoing AD Review of [3], this editing is on hold and queued. The same applies to further similar editing actions about terminology and parameter names, as triggered by recent updates to the Group OSCORE document in CoRE [4].
2. Based on discussions with Christian at IETF 113 (thanks!), the current Section 3 "Format of Scope" has been revised to define the new AIF data model upfront as intended to express both: i) permissions for members of OSCORE groups, as relevant for this document which specifies how to do it; and ii) permissions for Administrators of OSCORE groups, as relevant for draft-ietf-ace-oscore-gm-admin [5] where related details are specified.
As discussed for the latter case in [5], where the AIF Tperm would allow to express also a pattern of group names, the plan is to have the AIF Tperm as not necessarily a text string. For consistency, this requires to admit such a possibility already in Section 3.1 of [3], which currently considers only text strings. This editing is also on hold due to the ongoing AD Review of [3].
As anticipated in [2], I believe Göran would like to go through this latest, restructured version of the draft, and possibly come back with more comments.
Of course, more feedback from other folks is welcome!

Abstract: This document defines an application profile of the ACE framework for Authentication and Authorization, to request and provision keying material in group communication scenarios that are based on CoAP and are secured with Group Object Security for Constrained RESTful Environments (Group OSCORE). This application profile delegates the authentication and authorization of Clients, that join an OSCORE group through a Resource Server acting as Group Manager for that group. This application profile leverages protocol-specific transport profiles of ACE to achieve communication security, server authentication and proof-of-possession for a key owned by the Client and bound to an OAuth 2.0 Access Token.
