Hi Mattihas, sorry for the delay. it is indeed a possible API which we call "longstanding query" or "notification api" . Not yet available , but we have many requests for it so it wil come. my advice at the moment would be to do it yourself client side using say a DB state and fetching the data from our cache http://sindice.com/developers/cacheapi there is a timestamp which reflect the last updated date. you might want to send sindice specific messages to the http://groups.google.com/group/sindice-dev Cheers Gio On Fri, Oct 1, 2010 at 7:21 PM, Matthias Quasthoff <matthias--web@quasthoffs.de> wrote: > Dear all, > > is there a way of obtain the changes to RDF graphs over time, e.g., from > Sindice?
