Hi Sashikiran,
The easiest way to achieve this on the fly would be to download the OpenLink
Ajax Toolkit (OAT) VAD package from:
http://download.openlinksw.com/packages/5.0/virtuoso/oat_dav.vad
and install from the "System Admin" ->"Packages" tab of the Virtuoso Conductor
(http://localhost:8890/conductor) by browsing to the location of the file and
selecting the install option. You also need to ensure that the "rdf_mappers"
VAD package is installed from the list of available VAD packages with your
installation as this is not installed by default and contains the available
sponger cartridges including one for atom and other feed formats.
With the OAT and rdf_mapper VAD installed you can then load the OpenLink Data
Explorer (ODE) http://localhost:8890/ode and enter the URL to you Atom feed(s)
into the text window and request it be described, which will automatically
convert the atom to RDF which will be stored in the RDF store with a graph name
of the URL enter in ODE. You can check the graph has been created by checking
the "RDF"->"Graphs" tab of the Virtuoso Conductor.
If you want to process the Atom feeds using your own XSLT stylesheet indicated
below then you would need to use the Virtuoso xslt() function for doing this
and write your own Virtuoso PL/VSP functions for doing this as detailed at:
http://docs.openlinksw.com/virtuoso/fn_xslt.html
