The trio of postgraduate astrophysicists suggest a Messaging to Extraterrestrial Intelligence protocol (METI — PDF) for signal encoding, message length, information content, transmission method and periodicity. The protocol could be tested via a website that allows users to create, retrieve and decrypt sample messages that conform to the protocol — which also demonstrates communication across human cultural boundaries, they say."
