Google's 2005 analysis of values used in over a billion web pages reveal
@rel/@rev and @name reserved words that we don't support in RDFa:

http://code.google.com/webstats/2005-12/linkrels.html

Items on the @rel/@rev list that we don't support include:

shortcut, nofollow, made, search, top, author, edituri, file-list, and
service.post

We also don't support the following legacy @name values:

keywords, description, robots, generator, author, revisit-after,
copyright, progid, distribution, language

The complete analysis can be found here:

http://code.google.com/webstats/index.html

The study also states that the difference between @rel/@rev is probably
lost on many web authors... granted, there has never really been a
reason for web authors to care if they were using @rel/@rev. People will
start caring about the difference between @rel/@rev when they start
using RDFa...
