If model RSync is what you're looking for, the code in the RDFContextTool lib ( http://www.dbin.org/RDFContextTools.php but the code to use is really the one on the CVS) allows building a fantastically efficent one for RDF graphs (RDF RSync or R2Sync). Experimental results look really nice and the procedure is based exclusively on RDF theory (and the Minimum Self contained Graph theory [1], also used for digitally signign such fragments), not on the way some DB decides to store the graph (e.g. some DB specific de/serialization idiosyncrasy). I just need to find some time after the DBin release to get it out in in the public, but if someone is in urgent need of traffic efficient syncronization, please msg me I might be able to help right away :-) Giovanni [1] G.
