Funny thing about intuition: yours is different than mine.

I am not interested in defending this example if it does not ring true
for someone with more RDF and Semantic Web experience than I possess.
On the other hand, I have top admit to being a bit puzzled.

I came into this with the hope of becoming better versed in RDF and the
Semantic Web. Back in March I explained to TimBL, Ralph, Eric Miller,
and others that I did not GET the Semantic Web, or at least I did not get
the claims made by Semantic Web proponents that using RDF was in some
way superior to using structured markup.

So it was, a few weeks ago, that I worked with Dan to develop a simple example
that could be understood by mere mortals like me and yet still demonstrate 
the power
and simplicity of RDF. I wrote straightforward text to describe a scenario 
that is simple
enough for me to understand, and I solicited the help of Norm Walsh to 
produce the
example inputs. Dan wrote a GRDDL result that is much more complex than I 
had hoped,
but he said that it was an accurate RDF representation of the triple:
         "Stephen King" "is author of" "The Stand".

I am totally willing to accept the proposition that Dan and I got it wrong. 
I would love
to see the example that gets it right, and I only hope that I will be able 
to follow it.

However, I think that there has got to be something fundamentally wrong 
with this
Semantic Web thing if a technical writer with my experience working with DanC
and Norm Walsh couldn't put together a simple example and have it be 
interpreted
identically by all.

This exercise has reinforced my intuition that the Semantic Web is even 
more prone
to misinterpretation than common English prose embedded within XHTML. My 
intuition
tells me that
         http://www.stephenking.com/pages/works/stand/
is a web page which conveys the fact that "Stephen King" "is author of" 
"The Stand"
But, apparently, that is only because I don't know any better. My 
confidence has been
successfully undermined.

Regards,

Murray
