Recently I&#39;ve found ***[MessagePack][1]***, an alternative **binary** serialization format to Google&#39;s [Protocol Buffers](https://developers.google.com/protocol-buffers/) and [JSON](http://json.org/) which also outperforms both. 

Also there&#39;s the [BSON](http://bsonspec.org/) serialization format that is used by MongoDB for storing data.

Can somebody elaborate the *differences and the dis-/advantages of BSON vs MessagePack*? 

----------
Just to complete the list of performant binary serialization formats: There are also [**Gobs**][3] &lt;strike&gt;which are going to be the successor of Google&#39;s Protocol Buffers&lt;/strike&gt;. However &lt;strike&gt;in contrast to all the other mentioned formats those are not language-agnostic and rely on [Go&#39;s built-in reflection][4]&lt;/strike&gt; there are also Gobs libraries for at least on other language than Go.
