Should ev even be used?
In (X)HTML, the same values may be used as rev (“reverse relationship”) values, to indicate the relationship of the resource on which they appear to the target resource.However, given that the ‘rev’ attribute has been more often misused by authors than properly used (Google Code: Web Authoring Statistics: Link Relationships (http://code.google.com/webstats/2005-12/linkrels.html)) is it even a good idea to use rev at all?The short answer is unfortunately “NO”. Use of “rev” SHOULD be avoided.However, VoteLinks’ use of rev has been grandfathered since it was such an early use.No future microformats should be developed that use ‘rev’, and any use of ‘rev’ (apart from the “grand-fathered” case of VoteLinks) is deprecated in microformats.
