[goodrelations] Get 4 Billion Triples of Current GoodRelations RDF/XML Data for 20 Million Amazon Pages

Hi all,

It seems there is a quick and easy way to get a full RDF/XML 
representation of all 20 Million Amazon offers.

Here is how it will likely work:

1. Take the Amazon sitemap index files, as given by 

# Sitemap files
Sitemap: http://www.amazon.de/sitemap_index_0.xml
Sitemap: http://www.amazon.de/sitemap_index_1.xml
Sitemap: http://www.amazon.de/sitemap_index_2.xml
Sitemap: http://www.amazon.de/sitemap_index_3.xml
Sitemap: http://www.amazon.de/sitemap-manual-index.xml
Sitemap: http://www.amazon.de/sitemap_wishlist_index.xml

2. Take the individual sitemap files from all of those, e.g.

http://www.amazon.de/sitemap_page_0.xml.gz from 

<sitemapindex xmlns="http://www.google.com/schemas/sitemap/0.84">

3. Now, for each of those ca. 20 Million entries given as <loc> 
elements, e.g.



use the URIburner service (http://uriburner.com/sparql/) to extract the 
complete commercial meta-data in GoodRelations.

Note that not all URIs are current and that URIburner cannot produce 
GoodRelations data for not all pages, but it can for the majority of the 
ca. 20 Million pages.

You will get, on average, 200 GoodRelations triples per Amazon page, so 
the total will be in the order of magnitude of 4 billion !

(If you want to check it for yourself, try

select COUNT (*) WHERE
{?s ?p ?o.
FILTER (regex(?o, "^http://purl.org/goodrelations/v1#", "i") or 
regex(?p, "^http://purl.org/goodrelations/v1#", "i")) 

against the URI


Important: Using URIburner on the full set of Amazon URIs will likely 
impose a great load on the underlying server, operated by OpenLink 
Software. If you want to use this option, in particular for commercial 
purposes, please contact Kingsley Idehen before you start. His e-mail is 
<kidehen at openlinksw.com>.

Best wishes
