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 in plain HTML 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! Congrats to Kingsley and his team!
