triplestore with revisions

Question

I need to store RDF triples, while keeping track of modifications. Is there anything out there for this service? Alternatively, how would you keep track of revision while using

Answer 1

in addition to the other answers, also take a look at the Lensfield system (research software at the moment) developed by Jim Downing et al.. Lensfield will not only keep track of different versions of your data, but also of any scripts/transformation instructions you use to process your data and change your graph. In short, it's a mixture of version control, maven and make for semantic data. Maybe that helps.
