Re: [Rats] FW: [Cbor] 🔔 WGLC on draft-ietf-cbor-tags-oid-02

[Laurence Lundblade <[e-mail]>]

The question I have is whether there is any intent for these OIDs to be keys or labels in CBOR maps. In X.509/PKIX extensions are labeled by OIDs. Would there be similar use in CBOR?

Typically, CBOR map labels are integers and sometimes text strings. Having to pay attention to tags in map keys might be very inconvenient for some CBOR decoders, though that could be avoided in a given protocol by saying the map keys are byte strings that borrow tag 111 content eliminating the need for the tag.
