CORE

Summary

The CORE Working Group held an interim meeting to discuss the status of the YANG-SID document, address an inquiry from IANA regarding CoAP errata, get an update on the CoAP Target Attribute draft, and plan for the next steps for the CoAP-PM document. Key decisions were made regarding the YANG-SID document's status fields, and it was determined that no action was required for IANA registries concerning CoAP errata. Plans were set for upcoming Working Group Last Calls and a dedicated educational session for the CoAP-PM draft.

Key Discussion Points

YANG-SID Document Status Update:
- A design team meeting was held last Thursday to discuss potential ways forward.
- Item Status Field: Discussion centered on additional information in the item-status field. The team decided to revert to a simpler state but added an obsolete status, suggested by Rob, to manage SID assignments no longer used in a module version.
- Per-SID-File Status: The group opted for an explicit per-sid-file-status to denote whether a SID file is "published" or "unpublished," rather than deriving it from per-item-status entries or reflecting it in a file extension (which raised tool issues). This allows for circulating proposals for stable SID files without them being considered definitively published.
- Out of Scope Issues: Issues 144 and 147, primarily concerning annotation support, were deemed beyond the scope of the current document and will be addressed in future work, potentially requiring new experimentation and tool building.
- Next Steps: Authors will prepare a draft-ietf-core-sid-020 revision. This revision will incorporate outstanding tasks 139, 66, and 88, which are routine updates. A response will be drafted to Rob, asking him to review the -020 version, with subsequent versions (e.g., -021) to incorporate any further comments he may have. An updated version is expected within approximately two weeks.
IANA Errata on CoAP:
- The WG discussed a mail received from IANA regarding whether several approved CoAP-related errata reports should be linked in any of five IANA registries.
- The sense of those present was that linking these errata would not add substantial value or context to the registries themselves.
- Errata 4945 and 4954, which either modify a registry or are already noted, were deemed under control.
- Consensus was reached that no action is needed regarding linking these errata to IANA registries.
Target Attribute Draft Update:
- Marcus reported difficulties in submitting the updated Target Attribute draft (draft-ietf-core-target-attr) due to issues with the XML-to-RFC toolchain.
- Once successfully submitted, the draft is considered ready for Working Group Last Call (WGLC).
- It was proposed that the Target Attribute WGLC should be synchronized with the WGLC for the draft-ietf-core-coap-ad-hoc document.
- Jaime Jimenez will handle the coordination of both WGLCs.
CoAP-PM Document Next Steps:
- An agenda item for the next interim meeting (in two weeks) was planned.
- The intent is to provide a pedagogical overview of the building blocks and technologies used in the CoAP-PM document. This is aimed at helping CORE participants, who may be less familiar with IPPM technologies, better understand and evaluate the draft before considering working group adoption. Giuseppe (and other co-authors) will lead this presentation.

Decisions and Action Items

Decisions:

YANG-SID: The item-status field will be simplified but include an obsolete status. An explicit per-sid-file-status will be added to indicate publication state. Issues 144 and 147 (annotation support) are out of scope for the current document.
IANA Errata: No additional links are needed in IANA registries for the discussed CoAP errata reports.

Action Items:

YANG-SID Authors: Publish draft-ietf-core-sid-020, incorporating tasks 139, 66, and 88. Draft a response to Rob, asking him to review the -020 version.
Marcus: Reply to IANA conveying the working group's consensus that no action is needed regarding the CoAP errata.
Marcus: Submit the updated draft-ietf-core-target-attr as soon as toolchain issues are resolved.
Chairs (Jaime Jimenez): Coordinate the Working Group Last Call for draft-ietf-core-target-attr and draft-ietf-core-coap-ad-hoc once the Target Attribute update is posted.
Giuseppe (and CoAP-PM authors): Prepare a pedagogical overview presentation of the CoAP-PM document's building blocks for the next interim meeting.

Next Steps

The next revision of the YANG-SID document (draft-ietf-core-sid-020) is expected to be published shortly, with further iteration planned based on feedback.
Working Group Last Calls for draft-ietf-core-target-attr and draft-ietf-core-coap-ad-hoc will be initiated once the Target Attribute draft is updated.
The next interim meeting will feature a presentation on the CoAP-PM document to facilitate understanding prior to considering working group adoption.
