There is no escape of this "personal" context.   Take your "high resolution"as an example, how do you know if I am not wanting the high resolution in terms of the molecular structure of that book, instead of its content or image? You must define your 'resolution' before making it high.  You cannot say compare two things without setting the criteria of comparison.  In other word, you cannot say which thing is a better awww:representation better than the other.

I would think otherwise.  As long as there is a URI owner, it is fine.  
All the semantics are semantics expressed by that URI owner.  I have 
thought about this but I don't see there is any other solution. 
Transparent content negotiation might help but only on very complicated 
cases. At last, it is a communication between two parties with no 
previous knowledge of each other.
