Deprecating it is based on Ian noticing that it wasn't used correctly to date. I'm sure that's true, but it misses the point: if no tools make use of @rev, then of course the markup will be wrong often. But with RDFa parsers like SearchMonkey and others, there is now an incentive to write things correctly. I think if the url-shortening folks choose rev=canonical, publishers will figure out just fine, because the first thing they would do is check that it works (with a bookmarklet, a web service that checks for you, etc...) and correct their markup if it doesn't. The idea that markup gets dirty because it's not human-visible is true... but I suspect it's not the root cause. The root cause is that there's no feedback mechanism to reinforce good markup. You can provide a feedback mechanism using SearchMonkey or otherwise. -Ben
