Concise Binary Object Representation (CBOR, RFC 7049) extends the JavaScript Object Notation (JSON, RFC 8259) data interchange format to include binary data and an extensibility model, using a binary representation format that is easy to parse correctly. It has been picked up by a number of IETF efforts (e.g., CORE, ANIMA GRASP) as a message format.

• The IETF CBOR working group will update RFC 7049 to deal with existing errata. Security issues and clarifications may be addressed, but changes to the document will ensure backward compatibility for widespread deployed codebases. The resulting document will be targeted at becoming an Internet Standard.
• This WG falls under the IETF applications and real-time area.
