This is exactly what I am talking about so to summarize.... Composer + SPIN + Sparql up to the querying task... That is good news. Umm... Irene has been kind enough to give us options for triple storing persistent databases... we are looking into them to determine which would be the best candidate... So with the limited information that you know about our "proposed application" so maybe without even putting that into focus... Which triple store db (jenadb, sdb, sesame etc...) do you feel would "play nice" with Composer + SPIN + Sparql. P.S. I have never looked into SPIN and I am doing so after the writing of this message.
