We did it, after a couple of late nights and alot of planning, the University of Florida's VIVO is running 1.2 in SDB. SDB, or Sparql Database for JENA, has been best described to me as Jena's second iteration on semantic data stores. The first iteration, RDB, stored two tables for every model, one for general statements and one for reified statements. The SDB focuses on a single table for all triples. Main model triples are stored in "Triple" while named graph triples are stored in "Quad". We're very excited to see the new performance with VIVO 1.2. You can see the site here, vivo.ufl.edu.
