That would be great. Thanks for having taking the time to make a
concrete proposal and for collecting feedback like this.

My own personal experience (and I'm even some kind of RDF person) is
that, even though I have the mental model and back-story to justify
rel= vs property=, ... I did often find myself mixing them up in
practice, especially when returning to RDFa after a few months away.
I've been fortunate in that I've a lot of RDFa literate friends who'll
help me out in IRC and Skype, but a lot of our users won't.  If we can
find a way to avoid making publishers think about rel-vs-property, I'm
sure it'll make things easier for everyone...

cheers,

Dan
