Below is the chairs’ summary of what happened in CoRE at IETF102. Corrections (and additions that keep the summary form) appreciated. Detailed minutes are being prepared; see link to raw minutes below. Grüße, Carsten CoRE WG - Summary IETF102 ========================= * Video Recordings: [Session 1](https://www.youtube.com/watch?v=2i9VAOJq8LU), Session 2 not yet available * [Slides](https://datatracker.ietf.org/meeting/102/materials/slides-102-core-consolidated-slides/) * [Raw minutes](https://etherpad.tools.ietf.org/p/notes-ietf-102-core?useMonospaceFont=true) # CoRE @ IETF102 WG summary * draft-ietf-core-links-json-10 and draft-ietf-core-cocoa-03 are in IESG processing and are awaiting new versions from the authors. Side meetings at this meeting have made progress addressing some of the open issues from AD and IESG input. * draft-ietf-core-object-security-13 is in IESG processing and is waiting for a review from Eric Rescorla, with a view to Eric clearing the remaining DISCUSS held on the document. Technical Changes resulting from IESG and directorate inputs were discussed. Responsible AD Alexey triggered a second IETF last call to cover those changes. * draft-ietf-core-oscore-groupcomm-02 is nearing WG last call. The plan is to progress this independently from the related ACE documents as the membership and group key management can be done by other means (e.g., using a simple REST API). Before the WGLC another interop should be held (implementation draft then to be published based on outcome of the processing of basic OSCORE). * draft-ietf-core-echo-request-tag-02 requires a few more reviews; no formal dependency but it would be good to finish this approximately on the same timeline as OSCORE. * draft-ietf-core-resource-directory-14 was discussed, with some focus of the semantics of the incoming (registration) and outgoing (lookup) links. With several implementations becoming available An interop would be next; September/early October time frame is envisioned. Next step then could be WGLC. * draft-ietf-core-rd-dns-sd-02 was discussed (and later presented in DNSSD WG as well). Much of the discussion centered about how the rt= target attribute can be turned into a service type on the DNSSD side. (Later in the DNSSD meeting, the question came up whether that is the right pairing in the first place.) All DNSSD service types must be registered (15 ldh characters max); CoRE resource types can be registered (63 characters max) or can be URIs. Further work on this is needed, as is on the pairing of ins= and DNSSD instance identifiers. * The CoRECONF cluster (new old name for yang-cbor draft-ietf-core-yang-cbor-06, comi draft-ietf-core-comi-03, and sid draft-ietf-core-sid-04) has recently received reviews fro the netmod community; a few more from the CoRE side and maybe another interop would be good before WGLC of this cluster, envisioned to close before IETF103. draft-veillette-core-yang-library has a little more time. As a major technical change it was agreed to always start a yang-cbor tree with a SID delta base of 0. This has slight performance disadvantages, but makes handling the payloads much less error-prone. The CoRE WG is not the place to develop YANG modules that match this functionality. A group will initiate the steps toward a new WG, tentatively called Yang Of Things (yot). * draft-ietf-core-dev-urn-02 was presented, with a focus on the small changes needed for alignment with OMA LWM2M. There was some support for this alignment in the room. Jari Arkko will coordinate with OMA and report back. (end of Monday meeting) * draft-ietf-core-senml-16 is in AUTH48 as of 2018-07-19, RFC-to-be 8428. * A quick heads up from Roman Danyliw pointed to the 2nd WGLC of DOTS signaling draft-ietf-dots-signal-channel-21, which uses CoAP. Interested reviewers were found. * draft-keranen-core-senml-fetch-01 found a few reviewers. Interest to be confirmed on the mailing list, in the case of success followed by a call for WG adaption. * A procedural point about IANA registering of SenML fields was discussed. If a registrant is not interested in EXI, no attempt should be made to register a new XML/EXI schema name. Authors to check with IANA whether the schema could be stored with the registration. As the first exercise of the registry went less than perfectly, AUTH48 to be used to add a couple of clarifying sentences. * For stateless forward proxies, there was good interest to explore the option of introducing an extended token. The plan is to realize (WGLC) or dismiss (revert to separate option, now also called Extended Token) before Bangkok. * draft-ietf-core-too-many-reqs-02 has passed WGLC. Authors will fix typos and then publication will be requested (instead of a second WGLC we will use the IETF last call for any emerging WG comments). * draft-ietf-core-multipart-ct-01 is ready for WGLC. As thw WG tends to think this will be successful, early registration of the Content-Format codepoint will now be pursued (following the procedure for this). * draft-bormann-core-proactive-ct-00 received good support. Next step is WG adoption call on mailing list. The second meeting ran over time significantly. The remaining items on the agenda, CoRE interfaces, dynlink, pubsub, and protocol negotiation, as well as presentation and discussion of draft-jarvinen-core-fasor-00, will move to interim meetings. * CoRE will hold regular virtual interims starting from Aug 15. The regular date envisioned is every second Wednesday (with some gaps) at 0800 California time.
