It is incredibly tough. The manual steps in trade, down to scribbling a note on the back of a single original piece of A4 paper, are tedious and tediously documented, UCP for example https://en.wikipedia.org/wiki/Uniform_Customs_and_Practice_for_Documentary_Credits https://en.wikipedia.org/wiki/Uniform_Customs_and_Practice_f.... Maersk will be implementing a new standard of implementation here, replacing a standard that's been bootstrapped over centries. Expect an ISO or similar to be created to define it, with a lot of reach into the workflow of insurance companies and banking (LCs, etc). This would be an interesting area to 'disrupt' if you could catch early wind of the emerging standards and ride on the back of a new standard coming into implementation.
