Hello Steven
Discovering your excellent page at
http://www.w3.org/MarkUp/2009/rdfa-for-html-authors ... just in time
with recent Google's announcement!
About "Talking about People, Places and Things", just a remark. You
write "The city of Amsterdam doesn't have a URI".
Well, not quite so now. The entity "City of Amsterdam" *has* indeed
several (too many, actually) coined URIs, such as :
http://dbpedia.org/resource/Amsterdam
http://sws.geonames.org/2759793/
http://rdf.freebase.com/ns/guid.9202a8c04000641f8000000000004475
http://mpii.de/yago/resource/Amsterdam
http://sw.opencyc.org/2008/06/10/concept/Mx4rvViJppwpEbGdrcN5Y29ycA
All those being URIs for this same entity, de-referencable along with
their RDF description, and parts of the linked data cloud.
See http://linkeddata.org for more about it
So if your page could include reference to such URIs, it would be great
for the linked data community!
Good to keep the blank node approach you explain quite well for those
entities with really no URI. But there are less and less of those ...
Even Love has a URI ... http://dbpedia.org/resource/Love :-)
Best
Bernard
