Protocol Buffers

Protocol buffers is another way to serialize/deserialize data.

It was written by Google and supports Java, C++, Perl, and Python.

There website is at: http://code.google.com/p/protobuf/

I'm planning on trying this out for a c++ project I maintain where we need blindingly fast ( as fast we can get ) serialization, and de-serialization performance.

Once I've played with it, I'll post more information.
