I recommend we migrate Section 3. Vendor-defined Options of coap-misc I-D into core-coap I-D.

This would then become 5.10.11.

Carsten proposal: reserved a option number that first 2 bytes of data is an code point that is allocated by IANA. reserver another options for 3 bytes, 1 byte, etc. Need two sets of these numbers - one for critical and one for elective.

Action: Carsten will write up in COAP misc.

We may need vendor options for all meaningful combinations of "(not) safe to be forwarded without knowing it" and "(not) part of the cache key".

Text in section 3 of coap-misc-18, to be moved over to core-coap.

Consensus from the Vancouver WG meeting was:

  • Adopt the Jump feature from Section 3.2.1 of coap-misc-20
  • Adopt the new IANA policy from Section 3.2.4 however 2048 -> should also go through a light designated expert review to make sure the option is categorized correctly (critical, elective, safe, cache key)
  • Remove the current Fencepost mechanism from the draft

The "Option Jump" feature has now been added, and "Fenceposting" removed in coap-12.
