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

2010-04-28 Thread Martin Hepp (UniBW)

Hi Constatine,

Yes, I consider that good practice.

> I can't see the benefit this might give to any agent making use of 
the triples.


owl:imports means that the model shall include all axioms from the 
imported ontologies. Often (but not always), the same effect can be 
achieved by dereferencing the URIs of all conceptual elements mentioned 
in a document.


I know that some people in the LOD community don't think owl:imports is 
necessary, but I do. There have been lengthy discussions about that, but 
basically RDFa is just one of many syntactical variants for RDF, so 
there is no strong argument for arbitrarily omitting anything.


BTW, I just found that there are some other quirks in the markup. We 
already contacted the site owner and hope he will fix them shortly.


Best
Martin

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=&ItemPage=
   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=,
 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
