Perhaps, I've had some users who experienced very significant performance gains from moving from SQL metadata representations to RDF, but it depends on the efficiency of the original SQL representation. > 2) Scalability -- Our triplestore would be HUGE.

Beyond that it gets a bit sketchy. I'm currently looking at ways to make it scale to 10^9+ without specialising the store to a particular schema. - Steve
