Data serialization format
CBOR
Concise Binary Object Representation (CBOR) is a binary data serialization format loosely based on JSON authored by Carsten Bormann and Paul Hoffman. Like JSON, it allows the transmission of data objects that contain name–value pairs, but with size efficiency. This increases processing and transfer speeds at the cost of human readability. It is one of the data serialization layers for the Constrained Application Protocol (CoAP) and the data format on which COSE messages are based. It is also used in the Client-to-Authenticator Protocol (CTAP) within the scope of the FIDO2 project. CBOR is defined in IETF RFC 8949. CBOR was inspired by MessagePack, which was developed and promoted by Sadayuki Furuhashi. CBOR extended MessagePack, particularly by allowing to distinguish text strings from byte strings, which was implemented in 2013 in MessagePack.
