Hi everyone! Here's a snapshot of where I've got to with doing an updated usage record schema. It's massively incomplete when it comes to listing all the elements, but it's got some of the flavour of what I intended. The main things to note are that it defines a CompoundUsageRecord and an AtomicActivityUsageRecord (which is incomplete) that are both in effect subtypes of UsageRecord (which has a few elements associated with it) and that I've split apart the concepts of Memory and NodeCount into PeakMemory and AverageMemory (and PeakNC and AverageNC respectively). There are probably more useful concepts to identify, and there's certainly more work to do copying things across. I'm also trying to put in sane documentation comments as I go. In any case, comments/brickbats would be welcome before I invest much more time and effort into this. :-) (I'm also using a somewhat-proper namespace URI now.) Donal.
