Hey Vishal, if you mean a triple store with built-in provenance metadata, I'm not aware of any that provide this out-of-the-box.
However it should be possible to implement using SPARQL named graphs as this paper shows: http://static.usenix.org/event/tapp11/tech/final_files/Halpin.pdf This is not a triplestore but it uses a similar approach: http://www.datomic.com Martynas graphity.org On Mon, Oct 29, 2012 at 9:00 PM, Vishal Sinha <[email protected]> wrote: > Hi, > > I want to model a RDF graph such that I can query by temporal factors later, > for example: > - how the graph changed between 20th October 2012 to 30th October 2012.
