Re: URIs in @rel and @property...

Many good comments and good elephant finding and hunting :)

I'm still concerned about the complexity we would be introducing in 
@about and @resource when we already have safe CURIEs, meaning the use 
cases are already addressed, I believe.

That said, I also see the benefit of applying the general rule of CURIE 
falling back into URLS when the prefix isn't defined... that's kind of nice.

I'm not entirely sure which side I fall on right now, but if we have a 
very clear algorithm that we all agree on, I guess I could be convinced 
to go with this new URI-fallback mechanism.
