Hi, could you point me to where the list of "standard keys" is maintained? I'm a little unfamiliar with the purpose of importing from the NaPTAN datasets, so I've just copied over what I guessed to be useful. 'ModificationDateTime' was the header in the Bristol NaPTAN data so I used that. Happy to change it if you can point me in the direction of some guidance (the wiki doesn't include this header)
On your second point, I have included the date, so I'm a little confused about what you're trying to say.
