One of the experiments that I've been playing with is breaking the data file down into lots of mini files and combining them to test. This gives me the chance to build different data files in the future that are targeted at one or two books, rather than everything. It also makes it easier to find the bits I need when errata are released. So far it seems to be working. Recombining them is a simple .bat file in windows, or an Automator process on a Mac.
To avoid losing everything in the future, all of the general character creation bits are being backed up on GitHub:

I'm leaving out a lot of the spells and equipment for now to make sure the core elements are working. Thanks to the split files, it's really easy to add these into the correct places later.
