Yeah! Stefan wins the prize for being the first to
express, formally in RDF/XML:
The nearest airport to the person
whose email address is stefan@db.stanford.edu
has IATA code SFO.
(though he loses a style point or two for using a urn ;-)
Lots of other folks have provided the information
in such a way that I, a human with lots of heuristic
and contextual tools, can process it*. But Stefan
put his info straight into the Semantic Web,
requiring no further manual processing.
I invite folks to play around with the RDF validator
http://www.w3.org/RDF/Validator/
to get a feel for how RDF (and XML) works.
As Jim suggested, you might find writing in RDF/n3
http://www.w3.org/2000/10/swap/Primer
and converting it
http://swag.semanticweb.org/n3tordf
is easier than writing RDF/xml by hand.
Those and other resources are available in the "background references"
section of our home page.
