CBOR

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.
