Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi I posted this question to the UnQL mailing list (http://groups.google.com/group/unql/browse_thread/thread/ce538e3fd85fa769) and it was recommended I post it to the CouchDB list: In the same way that UnQL standardizes document database queries does anyone know of any work being done on a standardized document database synchronization protocol? It would be magical if heterogeneous document databases could seamlessly synchonize and replicate in CouchDB-like fashion. Cheers, Stuart -- Stuart Rackham
