Fair comparison
Universal Document vs JSON
JSON carries data structure but does not by itself define a human document lifecycle. UD combines human-readable document semantics with machine-readable structure.
Not a forced replacement
UD is designed to coexist with established formats. The practical question is which object should carry structure, state and lineage, and which formats should remain compatibility exports or required delivery formats.
