Well you can take in the language guide http://code.google.com/apis/protocolbuffers/docs/proto.html#options where it talks about custom options. It's just below the Options section. This shows how to do it for a message and you'll be using the FieldDescriptor to do this. One more thing to note is that you might consider looking into hibernate. It appears you are working in C ++ so this might not be an option for you. I do know the hibernate path works.
