Q.E.D. Hmm. You can transmit some textual encoding of the triples in a lossless way, yes. But you can't actually transmit the triples themselves. Compare sending a numeral in some text, using some numerical convention, vs. sending an actual number. Maybe if 'lossless' is the sole criterion, then numbers are IRs also, since the literal "123"^^xsd:number seems to be an encoding of the number one hundred and twenty three with perfect fidelity. But I'm betting that this isn't what was originally intended by the IR idea.
