So I've been to a number of talks lately where the size of the current (Sept 08 diagram) Linked Open Data cloud, in triples, has been stated - with numbers that vary quite widely. The esw wiki says 2B triples as of 2007, which isn't very useful given the growth we've seen in the past year -- I've also seen the various blog posts and mail threads saying why we shouldn't cit meaningless numbers and such - but frankly, I've recently been on a bunch of panels with DB guys, and I'd love to have a reasonable number to quote -- anyone have a good estimate of the size of the danged thing (number of triples in the whole as an RDF graph would be nice) -- would also be nice for general audiences where big numbers tend to impress and for research purposes (for example, we know how far we can compress the triples for an in memory approach we are playing with, but we want to figure out how much memory we need for the whole cloud - we want to know if we need to shell out for the 16G iphone) anyway, if anyone has a decent estimate, or even a smart educated guess, I'd love to hear it
