The abstract of the specification is:<\/p>\n<blockquote><p>\nThe Concise Binary Object Representation (CBOR, RFC 7049) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation.<\/p>\n<p>In CBOR, one point of extensibility is the definition of CBOR tags. RFC 7049 defines two tags for time: CBOR tag 0 (RFC 3339 date\/time string) and tag 1 (Posix &#8220;seconds since the epoch&#8221;). Since then, additional requirements have become known. This specification defines a CBOR tag for an RFC 3339 date text string, for applications needing a textual date representation without a time. It also defines a CBOR tag for days since the Posix epoch, for applications needing a numeric date representation without a time. It is intended as the reference document for the IANA registration of the CBOR tags defined.<\/p><\/blockquote>\n<p>The need for this arose for the ISO Mobile Driver&#8217;s License specification in the working group <a href=\"https:\/\/www.iso.org\/committee\/45144.html\">ISO\/IEC JTC 1\/SC 17<\/a> &#8220;Cards and security devices for personal identification&#8221;.<\/p>\n<p>The specification is available at:<\/p>\n<ul>\n<li><a href=\"https:\/\/tools.ietf.org\/html\/draft-ietf-cbor-date-tag-00\">https:\/\/tools.ietf.org\/html\/draft-ietf-cbor-date-tag-00<\/a><\/li>\n<\/ul>\n<p>An HTML-formatted version is also available at:<\/p>\n<ul>\n<li><a href=\"https:\/\/self-issued.info\/docs\/draft-ietf-cbor-date-tag-00.html\">https:\/\/self-issued.info\/docs\/draft-ietf-cbor-date-tag-00.html<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The IETF CBOR working group has adopted the specification Concise Binary Object Representation (CBOR) Tags for Date.
