WG documents status and issues (CA)

CBOR implementations survey (MCR)

CB: we need to write that draft fast to define different category implementations.
MCR: write a draft, ask people to self identify and tell us where we miss critical bits?
CB: yes

MCR: what to do with implementations where I don’t get responses?
FP: not much more we can do than just list them without features, if they don’t answer.
CA: if there are public issue tracker we can use that
MCR: first question “are you in the mailing list”
FP: On tooling, secretariat could help (already started a survey)
CB: open the wiki feature from the github repo of the draft. start filling it, based on what we know, and wait on them to fill more.

→MCR to start terminology draft.

Packed CBOR (CB)

CA: why would one have suffix override rump rather than having the data in the first place?
CB: rump entirely spelled out that would be weird, but rump could have ref to shared items.
MCR: CBOR protocol executed through a serie of steps.

Ira: Agree with hunch with prefix more important than suffix, and length also longer.

MCR: question about 2.2 and 2.3 tables. Table 1: negative number?
CB: no, N is negative, result is always positive
MCR: does not overlap?
CB: no, alternating
MCR: Ok.

MCR: Table 2 suffix reference. Don’t understand how that works?
CB: Tagging the rump.
MCR: Ok, so you are tagging the rest. Now I get it. Text need to be clearer.
FP: review would be great.
MCR: Yes.

MCR: ??
CB: for the first 16 values you have a single value encoding. Next you have 1 byte.

→CB: more examples
→MCR: review on mailing list?

CB: have the next version of the draft pretty quickly so please keep comments coming.

→CB to clean his implementation and share it.

Discriminated unions

CA: Anybody read the pre-draft?
CB: First time shown.

AOB

WG: Thank you Barry!
