All individual item URIs, e.g.
http://products.semweb.bestbuy.com/products/8182593/semanticweb.rdf
should be dereferenceable and return a RDF/XML representation with
the proper media type.
But the RDF obtained by dereferencing that URI includes:
xml:base="http://products.semweb.bestbuy.com/semanticweb.rdf";
which means that the actual product URI ends up as:
http://products.semweb.bestbuy.com/semanticweb.rdf#Offering_8182593
When fetching that, you get a 404.
All,
Martin should have said: BestBuy is now publishing RDF/XML :-)
Linked Data meme deployment is coming, of course. Stay tuned.
On an orthogonal note re. BestBuy and other Linked Data publishing
endeavors, HTML+RDFa is the way to go re. default metadata
representation (esp. if you prefer # based HTTP URIs as identifiers for
your entities / data objects / resources). Basically, RDF/XML needs to
continue its journey to the lower echelons of the Linked Data value
pyramid (sooner rather than later).
