However, the performance in such a loosely coupled scenario is - not surprisingly - orders of magnitude worse than in a centralized scenario, especially when the queries involve joins across multiple SPARQL endpoints. We are working on improving this situations as well ;-) Regards, PeterReceived on Friday, 26 March 2010 21:13:35 UTC
