## Summary

The CBOR Working Group met for an interim session with no specific agenda items, but used the opportunity to get a better understanding of the status of current documents and future work items. Key discussions revolved around the progress of CBOR-Time-Tag, CBOR-Pact, and the conceptual work for CBOR 2.0. Participants also briefly touched upon longer-term topics like map-like data structures and future CDDL versions.

## Key Discussion Points

*   **CBOR-Time-Tag:**
    *   The document's progress is largely dependent on the completion of the SEDATE work.
    *   The SEDATE effort is currently addressing interoperability issues with RFC 3339, which may require an update to RFC 3339 itself (though this is outside the WG's explicit charter).
    *   Despite these challenges, the parts of SEDATE relevant to CBOR-Time-Tag are considered stable enough for the Time-Tag document to proceed.
    *   The current sense is that SEDATE will progress quickly enough that Time-Tag can be pushed forward in conjunction with it, making the dependency moot. The document is already in use, so there is no immediate rush.
*   **CBOR-Pact:**
    *   The document is awaiting reviews and implementations to progress.
    *   One participant noted that their own review and implementation were still pending.
*   **CBOR 2.0:**
    *   There is currently no active Internet-Draft for CBOR 2.0, with the previous "freezer" document having expired.
    *   The next step requires implementation effort to validate the rough ideas outlined in the expired "freezer" document and associated slides.
    *   The goal is to complete this validation, learn from implementations, and adjust specifications before the Internet-Draft deadline for IETF 115.
*   **Map-like Data Structures:** This topic remains an open issue for the working group, though no urgent use case has yet driven specific work. It is anticipated to be addressed at some point.
*   **CDDL Work:** Discussions around the next version of CDDL are ongoing and may lead to additional activities beyond the main document.
*   **Cross-WG CBOR Use Cases:** A participant volunteered to prepare material on CBOR usage in other working groups and expressed interest in brainstorming this topic at a later time.

## Decisions and Action Items

*   The chair committed to prioritizing their pending review and implementation work for **CBOR-Pact**.
*   The chair agreed to update and resubmit the expired **CBOR 2.0 "freezer" document**, potentially incorporating content that is currently only available in slides, to improve its visibility.
*   Participants interested in brainstorming ideas for **CBOR usage in other working groups** were encouraged to reach out to the individual who proposed the topic, or to expect a wider call for discussion on the mailing list.

## Next Steps

*   The next scheduled interim meeting in two weeks will be conditional on agenda items being submitted. An announcement will be made if the meeting is cancelled.
*   One participant indicated they would not be present at the next meeting, but expected to have updates regarding **CDDL** for the meeting four weeks from now.
*   Continue implementation efforts to validate the conceptual work on **CBOR 2.0**.
