In my experience data interoperability issues are usually resolved by writing adapters, and using a datastore with strict integrity constraints. This is essentially what creating a blockchain transaction is. The chain code is responsible for running strong integrity constraints on the submitted data, and the client must adapt the data as required by the chain code before submitting a transaction. You can't get rid of the work required, but you can create a system that enforces the rules.
