Don't most foods now come with expiry dates? I'd write that on the top.
My cans only have "Best by" dates, which are not really expiration dates. (Supposedly the flavor is better if you don't go beyond the best by date; I can't say I've noticed any real differences one way or the other.) So long as the can is undamaged, canned food should be good (as in safe to eat) pretty nearly forever, as the canning process is designed to kill and seal out all the bacteria, etc. that cause spoilage. Leaky or bulging cans should, of course, be discarded regardless of any date on the can.
These dates are also almost always printed on the ends of the cans to begin with, too, so it's probably not necessary to redundantly write them there. :)
