I imagined it as a sort of purely conceptual piece, but that's a classic blunder in math pedagogy, so maybe examples are in order here too.
The intended context is that these are the first section of a longer text document that gets progressively more concrete and detailed, going from these philosophical goals to (very much WIP) technical ones, with each layer referring to previous ones for justification (chain of reasoning is important, because some of them get pretty weird). That would be where most of the meat is, and maybe I've been assuming that those will serve as examples that clarify the very abstract parts. So I'm reluctant to make this part longer. Maybe one of those side-by-side formats would be good with examples and explanations off to the right?
With what I've given you, maybe it's enough that people aren't actively confused on what I'm even saying. Like I said up front, this is primarily an exercise in whether I can convey the ideas at all. I've historically had trouble putting them into words at all. I know it's a little weird using this slack as basically a writing critique group, by that's where I am right now. :)
I almost posted, and still might, an even more abstract question about what even can serve as justification for, e.g., one set of data modeling primitives over another.
