CBOR Tags for Date Registered

IETF logoThe CBOR tags for the date representations defined by the “Concise Binary Object Representation (CBOR) Tags for Date” specification have been registered in the IANA Concise Binary Object Representation (CBOR) Tags registry. This means that they’re now ready for use by applications. In particular, the full-date tag requested for use by the ISO Mobile Driver’s License specification in the ISO/IEC JTC 1/SC 17 “Cards and security devices for personal identification” working group is now good to go.

FYI, I also updated the spec to incorporate a few editorial suggestions by Carsten Bormann. The new draft changed “positive or negative” to “unsigned or negative” and added an implementation note about the relationship to Modified Julian Dates. Thanks Carsten, for the useful feedback, as always!

It’s my sense that the spec is now ready for working group last call in the CBOR Working Group.

The specification is available at:
