Here is how I imagine our schemata.
Fixed typo in field name
Updated schemata
Updated JSON file and insert script to new schema
Adjusted 006MME to the new "blob" schema
Converted another json file
Converted all insert files
Changed bucket name to a single one
Fixed some errors in the json file (which python couldn't handle)
Insert script inserts only inserts into one bucket

And can parse more than one file at once.
