Before revision:  The current paper raises the similarly tantalizing question of how to test the validity of a candidate system for general odor reproduction, despite such systems still being far from viable. The reasons for the question being nontrivialare discussed , and a novel method is proposed , which involves ideas from recognition and imitation, taking advantage of the availability of near-perfect reproduction methods for sight and sound.
After revision:  The current paper raises the similarly tantalizing question of how to test the validity of a system claimed to reproduce arbitrary odors artificially, in a way recognizable to humans, in face of the unavailability of a general naming method for odors. Although odor reproduction systems are still far from being viable, the question of how to test candidates thereof is claimed to be interesting and nontrivial , and a novel method is proposed , which involves ideas from recognition and imitation, taking advantage of the availability of near-perfect reproduction methods for sight and sound.
