That's a lot of data, I wonder if there is a smart way of filtering it down. Perhaps an RDF version of "twitter" would be interesting, where you "follow" changes that you're interested in? You could even follow by possibly user, or by SPARQL query, and maybe accross multiple domains. > > Did anyone tried to tackle this problem already? > > Cheers! > y > > > [1] http://n2.talis.com/wiki/Changeset > >
