GVS could be used as a way to do frequent backups of a KnoBot store without wasting disk space. A usage szenario would be a non-public gvs-store to and a cron-job which uses curl to get the model from knobot and put it to gvs. gvs's aggregation service could be used as well, but would probably have to be enhanced to support password authentication. reto --------------020102010404080105040009 Content-Type: message/rfc822; name="Attached Message" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="Attached Message" Received: from m3.mxes.net ([unix socket]) by ms3.mxes.net (Cyrus v2.3.7) with LMTPA; Fri, 09 Mar 2007 11:26:21 -0500 X-Sieve: CMU Sieve 2.3 Return-Path: Received: from 216.86.168.176 by m3.mxes.net (bayesd) with LMTP id 1173457580-84930-1 for ; Fri, 9 Mar 2007 11:26:21 -0500 (EST) Received: from mxout-01.mxes.net (mxout-01.mxes.net [216.86.168.176]) by mxout-01.mxes.net (Postfix) with ESMTP id B923D33F580 for ; Fri, 9 Mar 2007 11:26:20 -0500 (EST) Received: from n24c.bullet.scd.yahoo.com (n24c.bullet.scd.yahoo.com [66.218.67.214]) by mxin.mxes.net (Postfix) with SMTP id 4503533F4D1 for ; Fri, 9 Mar 2007 11:26:18 -0500 (EST) Comment: DomainKeys?

It also allows to retrieve unions of graphs from multiple sources for an arbitrary point in time. GVS can be integrated into applications that need persistent, version-aware RDF storage, the main interface is com.hp.hpl.jena.gvs.Store[1]. The example class com.hp.hpl.jena.gvs.examples.FoafMerger[2] shows such a usage as well as the integrated merging of equivalent resources. GVS also includes a AJAX-Web-Application which uses a RESTfull interface to access a GVS store. This application allows getting triples about resources from different sources as well as to go back in time and explore previous believes. A public instance of the gvs web-interface is at http://gvs.hpl.hp.com/application/gvs-browser, we would like to invite you to check it out, open an account and share and revise your triples. Currently the application requires an XHTML capable browser and was tested with Firefox, it does not run with Internet Explorer. GVS is at a quite early state of development, and it is yet unclear if, when and how it will be integrated within Jena. Till now, little effort has been made to optimize performance and this will be a main field of activity in the near future. GVS is developed under the same open-source terms as Jena, currently the sources are available only in the gvs module of the jena CVS repository (jena.cvs.sourceforge.net:/cvsroot/jena) [3]. We are looking forward to your feedback and questions which can be sent to the Jena-Dev Mailing list with subject starting with [GVS].
