Yet more metadata statistics out - from Sindice

HI Peter, all

to add (a probably small element of discussion) to this

i am happy to say that last week we released on the frontpage some
analytics stats which are fresh updated every week.

At the moment they come from  500million+ web URLS. Maybe not much but
pls notice we ONLY retain web urld which return RDF, RDFa, Microdata,
Microforamts etc (and trow away trivial markup).

Next week we hope to release the detailed per domain stats.

General analytics (classes) :

Its all on the homepage on http://sindice.com (see analytics tab)

Note: sindice is NOT at this point wildly crawling the web but rather
is accepting (and acting immediately) submissions of sitemaps, pings
and RDF datasets. Please submit yours to see them indexed (and
refreshed) at a reasonable rate nowadays


cheers
