-[MessagePack](http://msgpack.org) is a binary serialization format. If you need a fast and compact alternative of JSON, MessagePack is your friend. For example, a small integer can be encoded in a single byte, and short strings only need a single byte prefix + the original byte array. MessagePack implementation is already available in various lanaguages (See also the list in http://msgpack.org) and works as a universal data format.
