In a nutshell, this is why we committed to industry standards from the get-go, since doing so reduces this kind of work to functionality orchestration :-) WebDAV, Atom Pub, GData etc.. have all existed inside Virtuoso for a long time, but on their own the net effect has sometimes been confusion (due to value pyramid inversion on the part of its beholders). We also see XMPP (which you've alluded to recently, and bugged about by Danbri for sometime) and XMPP++ (Google Wave) as interesting. Ditto PubSubHubBub etc.. Also note, replication and synchronization e.g., via transaction logs (in the most sophisticated cases) is something Virtuoso has handled across SQL DBMS engines that provide API access to transaction logs for eons, so this is all very familiar territory. I still remember confusion, at advent of blogging, when we indicated the existence of Atom and RSS aggregation and indexing support inside Virtuoso (sure you can Google up on that) :-) Giovanni: why isn't the RDFsync protocol (from yourself and Orri) part of this conversation? My silence during this conversation has been deliberate :-) -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
