RDFa actions in web browsers (UI)

There is an interesting discussion happening on the microformats-discuss
mailing list on if/how actions on semantic data should be defined by
website publishers:

http://microformats.org/discuss/mail/microformats-discuss/2007-August/010526.html

This discussion is important as we are attempting to create a
browser-agnostic method of marking up actions for semantic data
specified as Microformats, eRDF or RDFa. This discussion assumes that we
want to give publishers the power to define semantic data actions.

If a method is being defined to give publishers the power to specify
semantic data actions, somebody from the RDFa community should probably
be involved. :)
