anyone got any good resources on diff-ing of not-text? comparing what has changed since the last time you looked or what is different between what you're about to publish vs what has already been published in a node/wire system or other such 2D, visual heavy interface paradigm?

I am aware of some work on diffing s-expressions: • https://fosdem.org/2021/schedule/event/sexpressiondiff/ • https://github.com/stamourv/sexp-diff Once you have something decent for s-expressions, it's probably straightforward to port it to other data structures/formats.
