Dear all:

I just found out that the Virtuoso Sponger Technology is even more 
powerful than I thought.

Briefly: "Spongers" create rich GoodRelations (and other RDF) meta-data 
for existing Web pages on-the-fly. Other than traditional 
screen-scraping approaches, Spongers reuse public APIs and other 
techniques, so the data is of unprecedented degree of structure.

Now, this can be directly used in arbitrary queries... by simply using 
the URI of the *existing* HTML Web page in the FROM clause of a SPARQL 
query.

Example:

   
http://www.amazon.com/Semantic-Web-Real-World-Applications-Industry/dp/0387485309

is a Web page offering a book. Amazon does not yet produce GoodRelations 
meta-data on their pages.

If you go to

    http://uriburner.com/sparql

and paste the URI in the "Default Graph URI " field and select "Retrieve 
remote RDF for all missing source graphs", then a query like

   "SELECT * WHERE {?s ?p ?o} LIMIT 50"

returns a fully-fledged GoodRelations description for that page - as if 
Amazon was already supporting GoodRelations for each of its > 4 million 
items!

There are spongers for BestBuy, eBay, Zillow, and many other types of 
resources.

Wow!

Best wishes
