Hi Martin, all,

 the sitemap exposed is not a Semantic Sitemap

Semantic Sitemap: http://products.semweb.bestbuy.com/sitemap.xml

but simply gives the location of the dumps.

in theory if this information is exposed as linked data then one would
like to have a semantic sitemap exposed, which includes other details
e.g. a sparql endpoint some information on the datasets etc. [1]

has this been considered and decided against? should we just live with
it and fit sindice to do some guesswork and process those instead? (i
am not necessarely against this last solution really.. )

In other words are you suggesting the use of semantic sitemaps or
should we just come to term to this? The disavantage is that linked
data browser that wants to use an index to find information will be
able to do so less reliably (hope that our guesswork works)

Giovanni
