The Concise Binary Object Representation (CBOR) 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. These design goals make it different from earlier binary serializations such as ASN.1 and MessagePack.

RFC 2396 (1998) specifies that relative URIs like //foo get resolved as http://foo. This means, if you link a resource like http://example.ms/, @href could as well just point to //example.ms/.
