Data model types, interoperability at the semantical level … I agree: these topics are worthy of many PhD theses!
One thing that has always amazed me about the spoken language is that the space of all possible sounds we could conceivably use to represent any given thing, like a “spoon” for instance, is so large, with no schelling point, and yet we somehow magically all agree (99.9% of the time) to call it the same thing, with no central authority enforcing the consensus.
Perhaps if we could figure out how to reproduce that phenomenon for
data model types in the digital world, then VC interoperability would improve.
