Produpedia takes the sophisticated RDF tuples of DBpedia[1] and somewhat dumbs it down to tables of different categories. This allows for fine-grained search configs, easily shareable by URL. E.g. "List of Grand Prixs on the Nürburgring"[3], also linked on the main page.
Some more details are explained on the site itself.
Side note: What I would ultimately like to build - as a 2.0 verison, if you will - is an Open Data Product search engine with community edits, a free alternative to common commercial ones like Google Shopping, as in a blend of Geizhals.eu and Wikipedia. DBpedia and Wikidata[2] datasets (both related to Wikipedia infoboxes) are not very useful in regards to actual "products", so this is a first step towards that goal. If you think this sounds interesting, want to contribute or have an idea, please contact me!
