@rtn@chaos.social I'm familiar with it (and have used some of it), but it's not really what I'm looking for in the sense that it doesn't actually solve any of the hard problems!

Sure, the modules are modular, and you *could* manually assemble it into some sort of modular data management setup. But it leaves the "how" of that undefined (especially things like relational integrity), and that is precisely the thing I am trying to work out here 🙂
