Re: RDFSync 0.1

The problem is really general.. but there have been many mentioning 
applications for one such procedure. Not last look at the early postings 
by TBL and others referenced in the paper.

Anyway, scenario include but are not limited to scalable cluster of RDF 
DBs (powering similarly scalable web sites, semantic web services) 
especially in loose heterogeneous, P2P or grid environments; mobile 
devices syncing.
One for all, we will use it right away in DBin version 0.4 coming soon ( 
http://dbin.org ): RDFSync is used each time one client meets another in 
P2P group earlier, the entire graph surrounding a URI had to be passed 
at each p2p direct exchange. Not good as the data increased in the group.
