Shane,

and what about my idea that might also pacify Niklas, namely that 'license' would not be mapped against the xhv:license property as now but rather to dcterms:license? The fact of the matter is that, at least in the RDF world, *nobody* uses xhv:license for, well, license, everybody uses either dcterms or cc...

Cheers

Ivan

So, for example, an object could make it so '+' meant '-'.  Or worse yet, so '+' meant '*'.  At the time this was hailed as a brilliant piece of abstraction.  In reality it was idiotic. Some things need to be constant.

It does not mean http://www.example.org/randomURI/somepage#license.  I know this and I am thankful.  I know this in the same way I know that 'foaf:' is defined as a prefix for me, and that it means the right thing.  I wouldn't want that to change randomly either.
