[core] CoRE WG summary for IETF 120

[Marco Tiloca <[e-mail]>]

Hello WIT Area,

The CoRE WG focuses on application protocols that enable constrained 
nodes to participate, in particular the Constrained Application Protocol 
(CoAP). CoRE will meet on Wednesday, July 24, for a 2-hour session.

Procedurally, 2 documents are with the RFC Editor, 2 wait for the 
Shepherd write-up, and 4 more have completed their WG Last Call.

CoAP is designed to enable group communication; the main work items on 
revamping the main document ("groupcomm-bis") and certain security 
aspects should be completed soon, once some recently received, 
additional reviews are addressed.

A decade of use has shown the need for a few corrections and 
clarifications in various CoAP-related RFCs. These are being compiled as 
an Internet Draft ("corr-clar"), building on filed errata, open issues, 
and reported experience.

WG items on the agenda for IETF120 include the following topics: 
advancing the remaining documents of the CORECONF cluster (efficient 
YANG); Concise Resource Identifiers (CRIs) as compact equivalent of 
URIs; parameters for controlling the behavior of CoAP observations (RFC 
7641); means to indicate transports available to use for CoAP; DNS over 
CoAP together with related, supporting documents; CoAP group 
observations based on notification responses sent over multicast; topics 
related to the OSCORE security protocol (RFC 8613), as to its use at 
proxies and for nested message protection, and on updating OSCORE keying 
material (KUDOS protocol) and OSCORE identifiers.

Individual submissions on the agenda include the use of CoAP over the 
(DTN) Bundle Protocol (BP) and more generally in space.

CoRE will resume its biweekly interim meetings between IETF 120 and IETF 
121 on 2024-08-28; one objective is to make steady progress on corr-clar 
in each of the meetings.

Best,
/Marco
