MessagePack is more compact than JSON, but imposes limitations on array and integer sizes.On the other hand, it allows binary data and non-UTF-8 encoded strings. In JSON, map keys have to be strings, but in MessagePack there is no such limitation and any type can be a map key, including types like maps and arrays, and, like YAML, numbers.
Integer ~73%: C, C++, Python, C#, Java: Similar to Base64, but modified to avoid both non-alphanumeric characters (+ and /) and letters that might look ambiguous when printed (0 – zero, I – capital i, O – capital o and l – lower-case L). Base58 is used to represent bitcoin addresses.
Base64 encoding can be helpful when fairly lengthy identifying information is used in an HTTP environment. For example, a database persistence framework for Java objects might use Base64 encoding to encode a relatively large unique id (generally 128-bit UUIDs) into a string for use as an HTTP parameter in HTTP forms or HTTP GET URLs. Also, many ...
UTF-8-encoded, preceded by varint-encoded integer length of string in bytes Repeated value with the same tag or, for varint-encoded integers only, values packed contiguously and prefixed by tag and total byte length — Smile \x21
A tag of 2 indicates that the following byte string encodes an unsigned bignum. A tag of 32 indicates that the following text string is a URI as defined in RFC 3986. RFC 8746 defines tags 64–87 to encode homogeneous arrays of fixed-size integer or floating-point values as byte strings. The tag 55799 is allocated to mean "CBOR data follows".

The values of that byte are as below (for AMF0): Number - 0x00 (Encoded as IEEE 64-bit double-precision floating point number) Boolean - 0x01 (Encoded as a single byte of value 0x00 or 0x01) String - 0x02 (16-bit integer string length with UTF-8 string) Object - 0x03 (Set of key/value pairs) Null - 0x05; ECMA Array - 0x08 (32-bit entry count)
To send binary files through certain systems (such as email) that do not allow all data values, they are often translated into a plain text representation (using, for example, Base64). Encoding the data has the disadvantage of increasing the file size during the transfer (for example, using Base64 will increase the file's size by approximately ...
