Definition: CBOR (Concise Binary Object Representation), standardised in IETF RFC 8949, is a binary data-serialisation format designed for small code and message size, extending a JSON-like data model to binary encoding for compact, efficient interchange, notably used as the encoding basis for ISO/IEC 18013-5 mDoc credentials.
