That is a good question. Please shout up if this is currently in use. Either way I can leave the single method there if people have already built stuff with it.

Being able to get > slices of aggregated data as CVS sounds useful.. maybe json/xml also? Yes well taking slices of the datamart is essential - currently that is what mydatamart is doing - carving off chunks of data for a particular orgunit subtree for a particular set of periods. Strange though it might seem coming from me, I've not been tempted to do either an xml or json rendition. For this sort of data, compressed csv seems most appropriate.
