The discussion so far seems to indicate that a separate transformation
service, performing data aggregation on demand, would be a desirable
complement to the perfSONAR suite of tools. Of course, there are some
tradeoffs between required functionalities, performance and implementation
effort, which should be considered as well.

Kind regards,
