In looking at Jena source code it is clear that Jena natively supports Triples and Quads throughout the persistence and query layers. I was recently asked if Jena could support the notion of a Quint, and I didn't know the answer. I do see some use of Node[] in various places in the source, suggesting that "beyond-quads" might have been thought about, but it really isn't something you hear much talk of, especially when a simple reification can solve the problem. Really, the only reason to consider a quint over reification is purely for raw performance, and that is precisely the use case that is driving my question. I have a very large graph application with a specific need to extend the triple to contain qualifying information, and from what research I've been able to find, it seems to indicate that a quint will perform better than a reified quad or triple.
Thanks for any insight you may be able to offer, Patrick Hoeffel Software Engineer Intelligent Software Solutions (www.issinc.com<http://www.issinc.com>)
