Hi all,

>>> The Web of Linked
>>> Data shouldn't be about mass crawling (search engine style) etc...      
>> It has to be. How would you answer a query like "all offers for a book
>> written by a German author" without crawling the relevant data sets?

First question would be: which dataset has this information? Does amazon 
has it, or does it needs to be linked to other people dataset where you 
can find such information? (which brings all the question of 
disambiguation of entities, etc...)

In any case, there are multiple ways to endup with more or less the same 
result. Tell me if I am right, but I think that the current set of 
related cartridges only get data from a book URL? So, it is just 
converting data about a particular book, for a given URL, using some API 
(amazon in this case).

What about search URLs, using search APIs from the same services? I can 
certainly think about a cartridge that does just this: searching for 
items, and returning the resultsets in RDF using some ontologies. And 
then you use the current cartridge to get all the information about the 
items you care about in the resultset.

One thing is sure is that the expressiveness of your queries is bound to 
the expressiveness of the search API you query. So this is not the 
answer to all problems.

But one question: is it realists to think that anyone could query all 
amazon and ebay sites (US, CAN, and all the other countries) to convert 
everything? And if it endups being the case, how synching and 
maintenance could take place?

It really depends on the usecases, but there are much that can be done 
by leveraging all APIs in systems such as the Virtuoso sponger. I think 
that what you are talking about here will only happen when these 
services will want it to happen.


Take care,
