RE: www.shopforia.com exposes GoodRelations in RDFa for 104,000 items / 5 mio. triples

Looking at the example source, I'm curious what's going on here:

<div class="description" about="http://www.shopforia.com/" typeof="owl:Ontology">
   <div rel="owl:imports" resource="http://www.w3.org/2006/vcard/ns"></div>
   <div rel="owl:imports" resource="http://purl.org/goodrelations/v1"></div>

Is this considered good practise? I can't see the benefit this might give to any agent making use of the triples.

Subject: www.shopforia.com exposes GoodRelations in RDFa for 104,000 items / 5 mio. triples

Dear all:
I am happy to announce one of many new major sources of GoodRelations data:

http://www.shopforia.com/ recently added GoodRelations in RDFa to their 104,000 items pages in 26 categories:

Example:
http://www.shopforia.com/cgi-bin/apf4/apf4.cgi?Operation=ItemLookup&ItemId=B003DRBA3S

Sitemap: There seems to be no sitemap for the site, but you can reconstruct it by 1. crawling
        http://www.shopforia.com/cgi-bin/apf4/apf4.cgi?SearchIndex=<Category>&ItemPage=<n>  with n = 1...400 for Category = Apparel, Beauty etc. and 2. extracting all item links, which follow the pattern
        http://www.shopforia.com/cgi-bin/apf4/apf4.cgi?Operation=ItemLookup&ItemId=<ASIN>, with ASIN = e.g. B0009RL86E

Many items have EAN/UPC codes, which allows for powerful linking with product model data (features etc.).

I guess that the total amount of triples will be in the order of magnitude of 50 triples per page x 104,000 pages = 5,200,000 triples.


Best wishes

Martin Hepp
