If you're following this...

The excerpt below is from RDF-IG, the main comment being from Pat Hayes.

I think your comments at the recent FOAF meeting about attempts to describe 
the plot-lines of popular TV programs would be a perfect antidote for some 
of this debate (i.e. as an illustration of the logical point Pat makes) ...


>>The purpose of the Semantic Web is to provide man and machine with easy

>I would characterize it somewhat differently. The purpose of the SW is to 
>make propositional content available to machine processing on the Web. 
>Indeed, most of the time, that content will *correspond to* the facts of

>facts is a good question: as I said above, getting that correspondence
